This is a GTK2 question rather than a nim question. I hope some NIXER will
disregard that and lend a hand. I have returned to a cross-platform GUI nim
project after 6 months in the Javascript Wilderness. I discovered the GTK2
version of my module was exercising the check-resize callback many more times
than necessary.
I have been unsuccessful in finding the documentation for the check-resize
signal - such as when it is emitted and what is done to its window just prior
to that.
Eliding lots of detail, the signal is captured with:
discard handle.signalConnect("check-resize",SIGNAL_FUNC(resizeReq),nil)
where handle is the top level window reference.
The call back (placed up-source) is like this:
proc resizeReq(widget: gtk2.PWindow, data: Pgpointer) {.cdecl.} =
#steps not shown
var wid,hgt:gint
widget.get_size(wid.addr.Pgint,hgt.addr.Pgint)
#steps using wid and hgt to revise children in widget.
Run
When the user expands the window, how is the new size communicated to the
window? Does the expansion do a set_size prior to sending the signal? Are these
issues discussed anywhere?
