Set Touch Area of a Widget

htsmith19 · December 11, 2019 at 11:32 AM

Hi,

Is there a way of increasing the touch area of a widget, for instance a dropdown, without increasing the size of the widget.

Am I able to set an area around the widget where if touched will open the dropdown for example or notify the parent window.

Thanks,

Hi,

there is no default API for such a case.

But, you could create an invisible window behind the widget and react on touch input (WM_TOUCH). Depending on the widget you can tell it to expand (DROPDOWN). But I doubt that this is easy for all the widgets.

Another possibility is to draw the widget on your own. This way you can create it larger and draw only a small area.

Regards,
Sven
