Sometimes the window must be redraw. For Example, if the window size has changed and the programm change the positions of gadgets. Win98SE destroy the gadged in this case.

so easy redraw the window after the resizegadget():

Code: Select all

rec.rect 
getclientrect_(WindowID(0),@rec) ;Get the window-Size 
invalidaterect_(WindowID(0),@rec,#true) ;add the complete size to the update-list (#True=earse the background) 
updatewindow_(WindowID(0)) ;and update

GPI,

I think this is an easier away:

RedrawWindow_(WindowID(), 0, 0, #RDW_INVALIDATE)

You can use #RDW_ERASE | #RDW_INVALIDATE if you want to erase the background too.

Doesn't work! The Gadgets and the background are destroyed.

GPI,

It works correctly on a standard window - all the gadgets are redrawn, which is what should happen. Are you using a different style window?

standard WIN98SE.
I only change the Window-color, Fonts, size, etc. No special software.

Your solution does nothing on WIN98SE.

GPI,

That's odd! The description of RedrawWindow() in the AllAPI API-Guide says Windows 95 or later, but it might be wrong. If you can, please try one more version and let me know the result:

Code: Select all

RedrawWindow_(WindowID(), 0, 0, 7)
