Hi,
The splitter would be easier to use if Splitter::Clear() would remove splitter wall positions and minimum sizes (pixel and relative) in addition to the child references. The minpx is currently not cleared at all, even if Splitter::Reset() is called.
Please change as follows:
void Splitter::Clear() {
while(GetFirstChild())
RemoveChild(GetFirstChild());
pos.Clear();
mins.Clear();
minpx.Clear();
}
void Splitter::Reset() {
Clear();
style = -1;
width = 4;
vert = false;
}
Additionally, it would be very helpful, if removing a child by its Ctrl* would remove the respective pos, mins and minpx records in a way that frees the display area for the adjacent panels.
UPDATE:
I had something like this in mind for removing a panel:
void Splitter::Layout() {
Size sz = GetSize();
int count = GetChildCount();
if(count == 0)
return;
if(mins.GetCount()<count) mins.SetCount(count,0); // Added
if(minpx.GetCount()<count) minpx.SetCount(count,0); // Added
count--;
if(pos.GetCount() < count) {
pos.SetCount(count, 0);
for(int i = 0; i < count; i++)
and
void Splitter::Remove(Ctrl *ctrl) {
int n=0;
Ctrl *c=GetFirstChild();
while(c){
if(c==ctrl){
if(c->GetNext()) pos.Remove(n);
else if(n>=1) pos.Remove(n-1);
mins.Remove(n);
minpx.Remove(n);
RemoveChild(ctrl);
break;
}
c=c->GetNext();
n++;
}
}
// Tom

Well, why not. I have made some changes (the most important is to use reference instead of pointer in Remove to make it consistent with other methods).
