window size gadget does not do anything! (SOLVED)

I've specified that my window has a resize gadget using WFLG_SIZEGADGET, and that does work. But I am unable to actually resize the window using the gadget, and (unsurprisingly) no IDCMP_CHANGEWINDOW or IDCMP_NEWSIZE event is received.

This time I have pored over the AutoDocs, but have not found any hint as to why. As far as I am aware, I have not specified min/max window sizes, nor have I used IDCMP_SIZEVERIFY.

The odd thing is that ChangeWindowBox() works *unless* I specify WFLG_SIZEGADGET . When I do specify WFLG_SIZEGADGET, ChangeWindowBox() does cause an IDCMP_CHANGEWINDOW event, but the window size itself is unchanged! How is that for wierd?

You need to specify WA_MinWidth, WA_MaxWidth etc etc. At least that's how it works here.

@alfkil
It works now, thanks!
