Horizontal Slider
The Horizontal Slider control enables users to select a value along the slider's scale. The selected value can be entered as the value of a page source node (via a page source link; see Notes below). In the Styles & Properties Pane, you can set the slider's minimum and maximum values (see 'Horizontal Slider properties' below), and specify control actions to execute, either when the slider is being moved or when it has finished being moved.
The three ways in which control actions can be executed (based on the sliding action) are described below:
Action execution | Trigger Control Actions During Sliding | Slider's Trigger Interval (in ms) |
Actions triggered after sliding completed | false (default) | — |
Actions triggered continuously | true | 0 |
Actions triggered at interval | true | 1 – 10000 |
•When the control is associated with a data source node (page source link), placing the mouse over the control (in Page Design View) displays the associated node in a popup. •All page source links in the page source tree are displayed in a bold font. Tree nodes that are not page source links are displayed in normal font. •Placing the mouse over the page source link in the design tree displays information about the associated control. •To remove a data-source node association (and therefore the data in the control), right-click the control (in Page Design View) and click Unassign Page Source Link <NodeName>. •To reset a style or property (in the Styles & Properties Pane), select the property and click Reset in the pane's toolbar. •The values of several properties can be set by using XPath expressions. This allows values to be dynamic: that is, generated via calculations, or from data source nodes, at runtime. To set an XPath expression, click Edit XPath in the toolbar of the Styles & Properties Pane. •To edit the XPath expression of a style or property (in the Styles & Properties Pane), select the style or property, and click Edit XPath in the pane's toolbar. •To copy a control to another location in the design, press Ctrl and drag-and-drop the control to the desired copy location. •To assign specific properties for a control, define one or more classes for the control (via the Browser CSS Class property), and then assign rules for the class/es in an external CSS file (that you specify in the Browser Settings dialog). •A control's CSS properties can be defined in the Styles & Properties Pane and/or in an external CSS file. Those defined in the Styles & Properties Pane have priority. |
Horizontal Slider events
The OnSliding event is available. For a description of the actions that can be defined for Horizontal Slider events, see the Actions section.
Horizontal Slider properties
The control's properties are available in the Styles & Properties Pane, and are listed below in the order in which they appear.
The name is used to reference the control from elsewhere in the page or project. Double-click inside the value field to edit.
|
The All Styles property becomes visible if the All Styles setting of the More Project Settings dialog has been set to true. (The default of this setting is false.)
The property enables you to set all of the component's styles via a single XPath map expression, such as the two map expressions below:
map{ "Bold Text" : $XML1/R/@bold = "1", "Italic Text" : true(), "Text" : "hello", "Text Color" : "red", "Background Color" : $XML1/R/@background, "Text Size" : $XML1/R/@textsize }
map{ "Style Sheet" : "Sheet-1" }
Note the following points:
•When you enter a value for the All Styles property—even if it is not a map—all the styling properties of the current component in the Styles & Properties Pane will no longer be visible . •This is an advanced feature, so you must ensure that your XPath map expression is correct, both syntax and values. •You can enter the key–value pairs of the map in any order. •The key names are the names of style properties (or styles). In the first map above, for example, Bold Text and Text Size are style names. The styles that are available for a particular component are listed under that component in the Styles & Properties Pane. •You can also specify a style sheet to use, as shown in the second map above.
|
The value returned by the XPath expression is displayed in the control. This enables alternative ways to enter display values for certain controls. For example, a combo box could take its display value from either a page source node or the return value of the Get Value from XPath property.
Note: The $MTControlValue variable is not available for the generation of the value of the Get Value from XPath property. If used, then a validation error results.
|
Possible values are true or false. The property's default value is false. If set to true and the entered value is outside the slider's defined range of values, then the entered value is automatically corrected to a value from the range that is closest to the entered value. (The slider's defined range of values is set with the Slider Minimum Value and Slider Maximum Value properties.) For example, if the property's value is set to true, the slider's range of values is defined to be between 0 and 100 (the default range), and the slider's associated page source node contains a value of "somestring", then this value is automatically corrected to 0. If the node contained a value of 200, then its value would be auto-corrected to 100. The auto-correction happens immediately the out-of-range value is detected, for example, when the solution is opened or when the value is entered.
|
Sets the minimum value of the slider. Allowed values are -10000 to 10000. The default value is 0. Select one of the predefined numbers between 0 and 100, or enter an XPath expression.
|
Sets the maximum value of the slider. Allowed values are -10000 to 10000. The default value is 100. Select one of the predefined numbers between 0 and 100, or enter an XPath expression.
|
The Slider Color property sets the color of the slider's scale line when the slider is enabled. The default value is client-specific.
|
The Slider Color (Disabled) property sets the color of the slider's scale line and the slider's marker when the slider is disabled. The condition/s for enabling and disabling a slider is set on the slider's Enabled/Editable property. The property's default value is client-specific.
|
The Slider Thumb Color property sets the color of the slider's marker when the slider is enabled. The default value is client-specific.
|
If set to OnSliding, control actions are triggered during sliding (either continuously or at specified intervals). When set to OnSliding, the property Trigger Control Actions on Sliding Interval [ms] (see below) appears; you can set the trigger intervals here. If set to OnFinishEditing, control actions are triggered after sliding has finished. Default is OnFinishEditing.
|
Specifies the intervals, in milliseconds, at which control actions are triggered. The range of values is 0 to 10000. The default is 1000ms. Select a value from the dropdown list, or enter a value.
|
Click the Additional Dialog button to display the control's Actions dialog. You can set actions to perform when a control event is triggered. The control's event/s are predefined and each is shown in its own tab in the right-hand pane of the Actions dialog. A library of actions is displayed in the left-hand pane. You can drag an action from the left-hand pane into an event's tab and then define the properties of the action. For each event, multiple actions can be set up. They will be executed in the order in which they occur, from top to bottom.
After defining a control's actions, you can access and edit them at any time by clicking the property's Additional Dialog button. Alternatively, you can access a control event by right-clicking the control and selecting the control's event in the context menu that appears.
|
An XPath expression that should evaluate to true() or false(). If the expression evaluates to false()—and only if it evaluates to false()—then the control is not visible. If the expression evaluates to true() or returns some other value, then the control is visible. The default is true(). Double-click inside the value field, or click the XPath button, to enter or edit an XPath expression. The Visible property can be used to render an object visible or not depending upon whether an XPath expression evaluates to true(). As a result, the display of an object can be made to be dynamically dependent on the content or structure of data.
Note: For information about the visibility of spanned columns/rows, see Table Properties.
Note: The $MTControlValue variable is not available for the evaluation of the Visible property. If it is used, then a validation error results.
|
The control is either enabled or disabled, according to whether the value of the property is true (enabled) or false (disabled). The value can be entered directly (by selecting it in the combo box or by double-clicking in the value field and entering the value you want). The value can also be an XPath expression that evaluates to boolean true or false. The default value is true. Typically the XPath expression of the Enabled/Editable property of a control would check the presence or value of a node. If the expression evaluates to true, the control will be enabled.
|
Sets the background color of the object when the object is enabled. You can do one of the following to select the color:
•Click the color palette to select a background color •Select a color from the dropdown list of the combo box. If the cell contains a control, you might want to select the option Control's background color. •Double-click in the value field to enter a color code (for example, #FF0000), or click the XPath toolbar button and enter an XPath expression to generate the required text. To take up the background color of the control, enter the XPath expression: "control".
Note: You can set the background color of the cell to be the same as the background color of the control in the cell, by either: (i) selecting Control's background color in the property's combo box, or (ii) entering the XPath expression "control" in the property's value field.
Note: A control can be enabled/disabled according to context. For example, if in a form about personal details, the user enters an affirmative for the holding of life insurance, then the fields for details of the life insurance policy can be enabled; otherwise these fields can be disabled. To enable/disable a field, use the relevant control's Enabled/Editable property. To set a background color for when the object is disabled, use the Background Color (Disabled) property.
|
Sets the background color of the object when the object is disabled. You can do one of the following to select the color:
•Click the color palette to select a background color •Select a color from the dropdown list of the combo box •Double-click in the value field to enter a color code (for example, #FF0000), or click the XPath toolbar button and enter an XPath expression to generate the required text.
Note: A control can be enabled/disabled according to context. For example, if in a form about personal details, the user enters an affirmative for the holding of life insurance, then the fields for details of the life insurance policy can be enabled; otherwise these fields can be disabled. To enable/disable a field, use the relevant control's Enabled/Editable property. To set a background color for when the object is enabled, use the Background Color property.
|
Sets the text that appears as a tooltip when the end user hovers over the control with the mouse or long presses the control. A tooltip provides useful information to the end user about the control. Double-click inside the value field to edit. If an action has been set for a long press of the control, then no tooltip will be shown on a long press.
Note: Tooltips are not available on all controls, and for some controls they are not available on all platforms. On iOS, tooltips are not available for Edit Field or Signature controls.
|
This property applies in the case of some controls (such as images and vertical lines) to the control, in other cases (such as radio buttons and check boxes) to the text that accompanies the control. The property sets the horizontal alignment of the control or text to left, center, or right. Default is left for all controls except vertical lines, for which it is center. The property's value can also be specified via an XPath expression (which enables the value to be generated dynamically).
|
Sets the vertical alignment to top, middle, or bottom. Default is middle. The value can also be specified via an XPath expression (which enables the value to be generated dynamically). For Check Box controls, the property sets the vertical alignment of the check box relative to its text if the text is multiline (see the Multiline property)
|
Sets the width of the control. Select a value from the property's combo box. The following values are available:
•fill_parent: makes the control as wide as the parent, which could be, for example, a table cell or the page •wrap_content: makes the control only as wide as the control's content requires; when this value is selected, the property Max Control Width becomes available •wrap_content_longest_entry: is available for combo box controls and makes the combo box as wide as the longest content requires; when this property value is selected, the property Max Control Width becomes available •percent value: a percentage of the page width; select a value from the dropdown list, or enter a value directly •pixel, dp, or sp value: select a pixel, dp, or sp value from the dropdown list, or enter a value directly
In effect, fill_parent creates a maximum width, while wrap_content creates a minimum width. If the combo box is within a table cell, for example, fill_parent would let the combo box fill the cell whereas wrap_content might not fill the cell.
The default value is fill_parent for all controls except the following:
•Image and Chart: For these, the default is wrap_content. •Geolocation Map: The default is the smaller of the two values $MT_CanvasX and $MT_CanvasY. These two dynamic variables give, respectively, the width and height of the device's viewport. Since the default of both Control Height and Control Width are the same (in each case, the smaller of $MT_CanvasX and $MT_CanvasY), the default shape and size of the viewport in the control will always be a square with side equal to min($MT_CanvasX, $MT_CanvasY).

|
Sets the margin offsets of the control (or page) relative to the surrounding objects or to the borders of the containing object. Select a value in pixels, dp, or sp from the dropdown list of the combo box, or double-click in the value field to enter a length value. The specified offset will be created on all four sides of the control or page. If you wish to set a different margin for any of the four sides, expand the Margin property to display the individual margin properties (left, right, top and bottom), and set the different value. For example: If you set Margin to be 6px and Margin Bottom to be 12px, then the top, left and right margins will be 6px and the bottom margin will be 12px.
For information about the relationships between pixels, dp (device-independent pixels), and sp (scale-independent pixels), see Sizes: Pixels, DPI, DP, SP.
|
Sets the control's padding, which is the space between the control's border and the control's content. If the control is a table and the padding is set on a table row or column, then the padding is added to the margin of any control that is contained in the row or column; this increases the inset of the contained control and does not modify the size of table cells.
Select a value in pixels, dp, or sp from the dropdown list of the combo box, or double-click in the value field to enter a length value. The padding will be set on all four sides of the control. If you wish to set a different padding for any of the four sides, expand the Padding property to display the individual padding properties (left, right, top and bottom), and set the different value. For example: If you set Padding to be 6px and Padding Bottom to be 12px, then the top, left and right padding will be 6px and the bottom padding will be 12px.
For information about the relationships between pixels, dp (device-independent pixels), and sp (scale-independent pixels), see Sizes: Pixels, DPI, DP, SP.
|
The Tab Order property takes an integer as its value, or an XPath expression that evaluates to an integer. This integer number is the position of the control in the tab order sequence.
The tab order is the sequence in which controls receive the focus when the client-device user taps the Tab key. The entire tab order sequence can be set quickly and in the visual context of all controls of the page via the Page | Show/Define Tab Order menu command. The Tab Order property of individual controls sets the sequential position of that control only.
Note: The Tab Order feature is available on Web and Windows clients only.
|
The Style Sheet property sets the style sheet to use for the control. The dropdown list of the Style Sheet property's combo box displays all the user-created style sheets that have been defined in the project. Select the style sheet you want to use for the control. Alternatively, you can use an XPath expression to select the style sheet you want; this has the advantage that you can make the selection of the style sheet conditional (see Applying User-Created Style Sheets). See the section Style Sheets for more information.
|
The name of one or more CSS classes that you want to associate with this control. Use a space to assign multiple classes: LabelClassOne LabelClassTwo. These classes can then be used in a CSS file (specified in the Browser Settings dialog) to assign properties specifically for this control. You can also use an XPath expression to generate or fetch the names of the class(es).
