Size of popup menu

Hi,

Is there any way to get (or even set) the size of a popup menu? I would like to position it so that it is centered above the cursor.

Thanks,
Max

I don’t think that there is a direct way to get the size of a menu since it does not derive from wxWindow. The best that I have found to do in the past is to examine the width of the labels for the menu items to find the longest one and then do some rough calculations to get an approximate width of the menu.

Psuedo code: (self is window that owns the menu)

twidth, theight = self.GetTextExtent(longest_lbl)

twidth += 16 (approximate padding on left and right of label, this varies by platform)

if (using check items or using bitmaps in the menu):

twidth += 16 (checkitem/bmp width)

twidth += 5 (approximate amount of padding between bmp and label)
