How to reduce the size of the Context menu or TrackPopupMenu

(1/1)

Paul Yuen:
Hi

Can someone show me how to reduce the width of the Context menu ?  I have attached a screen shot of the Context menu (activated by right mouse click) . 

As shown,  the menu is very wide -- much wider than the menuitems' strings.   There are lots of blank space between the last character of the menuitems' string and the menu border.   How to reduce this width ?  Thank you in advance.

José Roca:
The only way is to make it owner draw and draw yourself the icons, text, etc. Not advisable because it is very complicated.

Paul Yuen:
Thank you Jose

Pierre Bellisle:
Hey Paul,

There is a nice example on PowerBASIC forum, see Bud Meyer pop-up menu.

Find @lpmis.itemWidth and divide it by 2 for the fun of it...

Pierre

Paul Yuen:
Many Thanks  Pierre

Wow , what an awesome owner draw menu.  The author did lot's of work on this menu
