The Label control allows to place a single line of text in the app view, dialog or frame. This control is mainly intended to be used with controls like the Email input, Phone input, Color input, etc.
The Label control provide the Input property, which can be use to associate the Label control with a specific input control, so when the user tap or click in the Label, the associated input is automatically focused.
In the case of the File input control, the control is not focused when the associated Label is clicked, but the appropriate file picker dialog appear to the user instead. See more information of the Input property.
This control has a default style, and, some control JavaScript properties (see below), can also changes the control style, not to mention the Classes property, that you can use to establish one or more CSS classes to be applied to the control.
In addition to that style, you can also set custom CSS rules for the control by using the IDE controls style inspector. If this is not enough, you can include any number of CSS stylesheets in the app by using the app files manager.
If you want to use CSS stylesheets, you need to know how to refer to the control, so take a look at the Runtime selectors help topic.
The Label control put at your disposition the below designtime properties or variables. Designtime means here that these properties are only available in designtime and not in runtime.
The Label control put at your disposition the below runtime properties or variables. You can set almost all these variables in designtime, and, they are also available to be use when the app is running. Note that we named here these variables in a capitalized way, because is like you can see it in the designtime control's inspector, however, at runtime we use the lower camel case way.
The Label control put at your disposition the below events handlers:
Designtime. Integer variable. The Top property stores the top position of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.
Designtime. Integer variable. The Left property stores the left position of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.
Designtime. Integer variable. The Width property stores the width of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.
Designtime. Integer variable. The Height property stores the height of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.
Designtime. Boolean variable. The Locked property determines if the control can be moved or resized in app view designer or not. Set a "false" value mean the control can be moved and resized. Set a "true" value (by default) mean the control cannot be moved nor resized. Remember that this control property is only for designtime and is not available in runtime.
Runtime. String variable. The Name control property stores the name of the Label control as you set in designtime. The Name property value must be unique for the same app view, dialog or frame, that is, it's possible to have more than one "label1" in the app, if that controls resides in different app views, dialogs or frames. Note that you must consider this variable as read only: change the name of a control in runtime can cause unexpected results.
Runtime. Mixed variable. The Event control property stores the "event" variable received in all the control events. This variable can contain the target (HTML element of the control) that fire the event and more useful stuff.
Runtime. Mixed variable. The Text control property stores the text that is show to the user. Can contain a bit of HTML if needed.
Runtime. String variable. The Title control property stores some small but descriptive text, mainly to be used to be show that text when the user place the mouse cursor into the control.
Runtime. String variable. The Classes control property stores one or more additionals CSS classes (space separated) to be applied to the control.
Runtime. Boolean variable. The Hidden control property determines if the control appear visible to the user or not. Set to "true" to hide the control, or to "false" to show the control (by default).
Runtime. String variable. The Input control property can be set at designtime or runtime with the name of an input control. Then, when the Label control is clicked by the user, the associated control is automatically focused. In the case of the File input control, the control is not focused when the associated Label is clicked, but the appropriate file picker dialog appear to the user instead.
Note that, for File input controls, the "Input" property of the Label control, must be suffixed by "-input", so, if you want to set the "Input" property for a "file1" File input control, the "Input" property of the Label control must be: "file1-input".
Runtime. String variable. The LeftIcon control property allows to establish an optional icon to be show at the left of the Label text. Remember that you are free to use any of the available icons in the Font Awesome library, which is one of the available libraries in the DecSoft App Builder created apps.
Runtime. String variable. The RightIcon control property allows to establish an optional icon to be show at the right of the Label text. Remember that you are free to use any of the available icons in the Font Awesome library, which is one of the available libraries in the DecSoft App Builder created apps.
The Click event handler is fired when the user click or tap into the Label control. See also the available events variables.
The DblClick (Double Click) event handler is fired when the user double click or double tap into the Label control. See also the available events variables.
The MouseUp event handler is fired when the user up the mouse into the Label control. See also the available events variables.
The MouseDown event handler is fired when the user down the mouse into the Label control. See also the available events variables.
The MouseMove event handler is fired when the user move the mouse into the Label control. See also the available events variables.
The MouseEnter event handler is fired when the user enter the mouse into the Label control. See also the available events variables.
The MouseLeave event handler is fired when the user leave the mouse from the Label control. See also the available events variables.
The ContextMenu event handler is fired when the browser must shown the context menu of the the Label control, which occur when the user click with the right mouse button into the Label control. See also the available events variables.
The below JavaScript variables are available in all the referred Label control events handlers:
| Name | Type | Description |
|---|---|---|
| event | Mixed | This variable is received in almost all control events. You can use this variable to stop the propagation of the event, to access the HTML element who fire the event and more. |
| self | Object | Stores the control object. This is a shortcut to the control variable, and it's available since we are talking about specific control events. |
| view | Object |
Stores the current app view or dialog. This variable allow us to access to that view or dialog properties and methods and also their controls properties and methods. For example, you can access to a control properties using the variable "view.yourControlName", suposing the control is named "yourControlName". |
| views | Object | Stores all the loaded app views. Note that loaded views mean that the app views has been previously show to the user. It's possible to access to the app view controls properties like "views.view1.yourControlName", suposing the view is named "view1" and the control is named "yourControlName". In the same way we can access to other controls of the view and to other loaded views and their controls. |
| frames | Object | Stores all the app frames. You can use this variable to access to all the app frames and their controls. |
| dialogs | Object | Stores all the app dialogs. You can use this variable to access to all the app dialogs and their controls. |
| app | Object | Stores all the app properties and methods. You can use this variable to access to all the app properties and app methods. |
