Okay, I'm currently using iupdrvBaseLayoutUpdateMethod to be my layout
for everything. I have a very simple test consisting of a window and
label.
int main(int argc, const char* argv[])
{
IupOpen(&argc, &argv);
Ihandle* label = IupLabel("Hello");
Ihandle* dialog = IupDialog(label);
IupShowXY(dialog, IUP_CENTER, IUP_CENTER);
IupMainLoop();
...
}
My current problem is the label is getting clipped.
When I step through iupdrvBaseLayoutUpdateMethod(),
ih->currentwidth is 26 and
ih->currentheight is 6
In Cocoa, the minimum dimensions to correctly show the label "Hello" are 36x17.
So if I take Iup's values and apply them, my label gets clipped
because the box is too small.
What should I be doing here?
