hello
I don't think this is a bug. I think i'm a not using it correctly.
I have designed a simple layout ( 2 buttons ) and i want to draw it in a splitterCtrl. Here a minimalist version of my code that produce the problem. The background of the layout is not painted correctly in the splitterCtrl.
TopWindow a;
Splitter b;
WithMyLayout<Ctrl> c;
WithMyLayout<Ctrl> d;
CtrlLayout(c);
CtrlLayout(d);
b.Vert(c, d);
a.Add(b);
a.Run()
Thanks for your help.

How can I invert colours of splitter bar when I drag (change position) with mouse? This mechanism like as in windows or linux when change window sizes in optimized mode (when I change windows size is paint only rectangle wich I drag without paint all window form... and in the end full refreshing window form with new size)?

hello all. I have an other problems with splitters, layouts and GLCtrl...
here a little example (the same as before  )
TopWindow a;
Splitter b;
Withbug1Layout<ParentCtrl> c;
Withbug1Layout<ParentCtrl> d;
CtrlLayout(c);
CtrlLayout(d);
b.Vert(c, d);
a.Add(b);
a.Run();
There is a GLCtrl on the layout like this
LAYOUT(bug1Layout, 184, 204)
ITEM(GLCtrl, dv___0, RightPosZ(12, 104).BottomPosZ(8, 104))
ITEM(Button, dv___1, LeftPosZ(8, 64).TopPosZ(8, 68))
END_LAYOUT
The problem is : the GLCtrl is not reshaped when i move the splitter bar.
Thanks for your help

I confirm that it is not the problem. I have tried all springs positions but it doesn't change anything.
For example, if i replace the GLCtrl by a LineEdit or other control : there is no problem of resizing...
LAYOUT(3DViewer, 412, 320)
ITEM(GLCtrl, opengl, HSizePosZ(20, 4).VSizePosZ(20, 4))
ITEM(Label, dv___1, SetLabel(t_("- :")).HSizePosZ(20, 4).TopPosZ(0, 20))
ITEM(Button, dv___2, LeftPosZ(0, 16).TopPosZ(20, 16))
END_LAYOUT |

Uhmm... that one happened some time ago... and it was solved.
I'll investigate a bit more

Well, that's strange, because before it worked... If you resize the splitter, glctrl don't update... but it does as soon as you move the full main window.
Did some event handling change in the meanwhile ?

Well.. a solution is found, but I don't know why behaviour changed. In X11Wnd.cpp, from line 963 :
// Synchronizes the native windows inside ctrls
void Ctrl::SyncNativeWindows(void)
{
ArrayMap<Window, Ctrl::XWindow>& xwindows = Xwindow();
for(int i = 0; i < xwindows.GetCount(); i++)
{
XWindow &xw = xwindows[i];
Window w = xwindows.GetKey(i);
if(xw.ctrl && xw.ctrl->parent && w)
{
Window dummy;
int x, y;
unsigned int width, height, border, depth;
XGetGeometry(Xdisplay, w, &dummy, &x, &y, &width, &height, &border, &depth);
Rect r = xw.ctrl->GetRectInParentWindow();
if( (x != r.left || y != r.top) && ((int)width == r.Width() && (int)height == r.Height()))
XMoveWindow(Xdisplay, w, r.left, r.top);
else if( (x == r.left || y == r.top) && ((int)width != r.Width() || (int)height != r.Height()))
===> HERE XMoveResizeWindow(Xdisplay, w, r.left, r.top, r.Width(), r.Height());
// XResizeWindow(Xdisplay, w, r.Width(), r.Height());
else if( x != r.left || y != r.top || (int)width != r.Width() || (int)height != r.Height())
XMoveResizeWindow(Xdisplay, w, r.left, r.top, r.Width(), r.Height());
}
}
} // END Ctrl::SyncNativeWindows()
I had to replace the XResizeWindow() with XMoveResizeWindow() (the one commented out). That's weird, but no time now to investigate more
Ciao

Well.... I'm becoming blind
Found the true bug, it was an bad '||' instead of '&&'.
Here the patched function...
// Synchronizes the native windows inside ctrls
void Ctrl::SyncNativeWindows(void)
{
ArrayMap<Window, Ctrl::XWindow>& xwindows = Xwindow();
for(int i = 0; i < xwindows.GetCount(); i++)
{
XWindow &xw = xwindows[i];
Window w = xwindows.GetKey(i);
if(xw.ctrl && xw.ctrl->parent && w)
{
Window dummy;
int x, y;
unsigned int width, height, border, depth;
XGetGeometry(Xdisplay, w, &dummy, &x, &y, &width, &height, &border, &depth);
Rect r = xw.ctrl->GetRectInParentWindow();
if( (x != r.left || y != r.top) && ((int)width == r.Width() && (int)height == r.Height()))
XMoveWindow(Xdisplay, w, r.left, r.top);
===>HERE else if( (x == r.left && y == r.top) && ((int)width != r.Width() || (int)height != r.Height()))
XResizeWindow(Xdisplay, w, r.Width(), r.Height());
else if( x != r.left || y != r.top || (int)width != r.Width() || (int)height != r.Height())
XMoveResizeWindow(Xdisplay, w, r.left, r.top, r.Width(), r.Height());
}
}
} // END Ctrl::SyncNativeWindows()
