Description

The Label is one of the most versatile components. It can display text, images, or both. Its text can be HTML formatted (like most components). It can even be made to respond to user interaction through its events.

Labels are one of the most common components that you will want to add  dynamic properties  to. For instance, you can put an integer dynamic property "state" on a label, and then bind the text to be "On" when the state=1 and "Off" otherwise, using an expression binding. Bind the background color to be red when the state is 0, and green when the state is 1 using a property binding. Now you have a re-usable binary state indicator. While you could have used the Multi-State Indicator to achieve the same effect, the exercise is good practice for creating custom components. You can see how the flexibility of bindings and dynamic properties make the Label extremely versatile.

Event Handlers
 mouse
 mouseClicked

This event signifies a mouse click on the source component. A mouse click the combination of a mouse press and a mouse release, both of which must have occurred over the source component. Note that this event fires after the pressed and released events have fired.

.sourceThe component that fired this event
.buttonThe code for the button that caused this event to fire.
.clickCountThe number of mouse clicks associated with this event.
.xThe x-coordinate (with respect to the source component) of this mouse event.
.yThe y-coordinate (with respect to the source component) of this mouse event.
.popupTriggerReturns True (1) if this mouse event is a popup trigger. What constitutes a popup trigger is operating system dependent, which is why this abstraction exists.
.altDownTrue (1) if the Alt key was held down during this event, false (0) otherwise.
.controlDownTrue (1) if the Control key was held down during this event, false (0) otherwise.
.shiftDownTrue (1) if the Shift key was held down during this event, false (0) otherwise.
 mouseEntered

This event fires when the mouse enters the space over the source component.

.shiftDownTrue (1) if the Shift key was held down during this event, false (0) otherwise.
 mouseExited

This event fires when the mouse leaves the space over the source component.

 propertyChange
 propertyChange

Fires whenever a bindable property of the source component changes. This works for standard and custom (dynamic) properties.

.newValueThe new value that this property changed to.
.oldValueThe value that this property was before it changed. Note that not all components include an accurate oldValue in their events.
.propertyNameThe name of the property that changed. NOTE: remember to always filter out these events for the property that you are looking for! Components often have many properties that change.
