Events associated with Chart controls

Default events

Events supported by WINDEV and WINDEV Mobile

In a window, WINDEV and WINDEV Mobile manage the following events by default (in order of appearance in the code editor):

Event	Runtime condition

Initialization	Executed when the window is opened. (*)
Click	Run during a mouse click on the Chart control.
Before displaying the tooltip	Run in an iPhone/iPad application before displaying the tooltip when pressing a chart value with a finger. This event is used to start a specific procedure, for example.

(*) By default, the "Initialization" event of each control is executed according to the order in which the controls were created in the window. To modify this runtime order:

On the "Window" tab, in the "Order" group, click "Initialization".
In the window that appears, use the arrows on the right to change the order in which the controls are initialized.

Events available in the report editor

The following events appear by default in the report editor:

Event	Runtime condition
