Detailed Description

Build a default widget for a given action using its Qt properties.

It should be good enough in most of the case.

The default widget contains:

• a title with the action icon, name and an information button
• the parameter ObjectController that allows you to edit/modify all the action parameters
• apply and revert buttons (the button frame)

The information button shows a dialog with the action classification, a description, the list of parameters and their properties, and the current target component names (inputs),

The button frame contains an "Apply" and a "Revert" button. The Apply button updates the action properties using the value entered by the user in the GUI. I.e., its clicked() signal is connected the the action apply() slot. The revert button resets the values in GUI to the initial values (all modification in the GUI are cancelled). You can easily show or hide the button frame using setButtonVisibility(). You can also customize the "Apply" button text using setApplyButtonText().

update() updates the widget using the actual/current properties and target of the action. This method should be called by an action in the overriden getWidget method. A typical getWidget() method of an action should use the lazy instantiation pattern to instantiate ActionWidget the first time it is called, and call the ActionWidget instance update() method for any subsequent calls.

If you do not want to wait for the user to click on the apply button (or if this button is hidden) and you want the value of the action's property/parameter to be updated everytime there is a change in the GUI, call setAutoUpdateProperty(true) (default is false);
