PtMenu positioning

Serge_Yuschenko1 · January 10, 2003, 6:56pm

Hi,

I’m trying to position a menu beneath of a menu button. It works when the button is a child of PtMenu widget, but if the button is placed on a PtMenuBar the menu is always appears at the top of the screen. No matter whether I set Pt_MENU_RIGHT, Pt_MENU_UP or Pt_MENU_DOWN. Am I doing something wrong or Pt_ARG_BUTTON_TYPE works only for PtMenu children?

Thanks,

Serge

Add the following line into the menu_post() before the PtRealizeWidget():
PtPositionMenu( (PtWidget_t*)data, NULL );
-Misha.

Add the following line into the menu_post() before
the PtRealizeWidget():
PtPositionMenu( (PtWidget_t*)data, NULL );
-Misha.

Thank you Misha. Just did. What misled me at first is the proper positioning of submenus.
