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 supported in WEBDEV

The following events appear by default in the code editor of a WEBDEV page:

Event	Runtime condition

Initialization (Server code)	Executed when the page is opened.
Loading (Browser code)	Run whenever the image of the chart is loaded and displayed by the browser.
Click on the image (Browser code)	Executed when the user clicks the Chart control.

Events available in the report editor

The following events appear by default in the report editor:

Event	Runtime condition

Initialization	Executed when initializing the report. When starting a report (including during a test), the events are run in the following order: "Opening" event of the report. "Initialization" event of report blocks. "Initialization" event of the controls.
Before printing	Executed before field printing.
Click	Executed when clicking the control. The click on the control is available in the report viewer only. A star allows the user to easily identify the clickable controls.

Optional events

Several optional events can be added.

To add an optional event:

Select the desired control.
Display the code window of this control (F2 key).
Click the link "Add other events to xxx" at the bottom of the window code, after the last event.
All the optional events available for the control are displayed.
Check the optional event to add and validate.
Note: Several optional events can be selected.
The selected optional event is automatically added to the events managed by the control.

To disable an optional event, simply perform the same operations to display the list of optional events. Then simply uncheck the optional events to delete.
Note: If the deactivated code contains WLanguage code, this code is automatically deleted..

You can manage, for example:

the mouse hover over the control,
left mouse button down, up, double click,
right mouse button down, up, double click,
mouse wheel, etc.

For more details, see the Optional events.

Optional events specific to the Chart controls

WINDEV proposes two optional events specific to the Chart controls:

Event	Runtime condition

Horizontal zoom	Run during a zoom in a Chart control. This event is run: if only the horizontal zoom is enabled. whether the horizontal zoom and the vertical zoom are enabled.
Vertical zoom	Run during a zoom in a Chart control. This event is run: if only the vertical zoom is enabled. whether the horizontal zoom and the vertical zoom are enabled.

For example, these zoom events can be used to manage the zoom in the image overlaid on the chart.
