Package: libwftk-0.7
Version: 0.7.1-5
Severity: normal
There are 3 ways to setup a picture in a setup button. I assume that it is
supposed to be equivalent given only for convenience. You can setup a
pushbutton via a resource name, a resource reference or a surface.
I browsed through the code and I discovered that in the third case there is
a scaling going on. However if you call the setUpPic() before the layout
manager (pack()) (BUG_TYPE == 1) there is no effect premasumably because the
widget has no size. The other methods are working correctly (BUG_TYPE == 0).
If you setUpPic() after the packing (BUG_TYPE == 3) there is an extra scaling
going
on that results into different visual effect than using the other type of
setUpPic() after the pack() (BUG_TYPE == 2)
To summarize:
BUG_TYPE set{Up|Down}Pic() before pack() Result
0 resource yes ok
2 resource no ok
1 surface yes nothing
3 surface no incorrect scaling
I can dig into it and produce a patch if there is sufficient interest.
