Here, the section clicked by the user is pulled out by the application.
To implement this behavior, all you have to do is use grInfoXY (to identify the section clicked) and grPiePullOut (to pull out the section).
WM Click on Chart Cross-platform examples (WINDEV Mobile): WM Click on Chart
[ + ] The "WM Click on Chart" example proposes a solution for pulling out the sections of a Pie chart via a simple click.
This example includes a control template named "TPLC_PullOutChart". This control template is used to pull out the chart sections via a simple click.
To include this feature in another application, all you have to do is import the "TPLC_PullOutChart" template.
