Selection changes before LostFocus() is called [message #13226]

Hello.

Situation:
- ArrayCtrl <-- No Focus
- LineEdit <-- Has Focus

Now selecting an other row in the ArrayCtrl results in changing the selection before LineEdit::LostFocus() is called.

Is this normal behaviour?

Using a TreeCtrl LineEdit::LostFocus() is called before the selection changes.

Testcase will follow...

LostFocus is invoked by CtrlCore, it is very unlikely (alhough not impossible) that it would behave differently for different derived classes...

Ok. For me it looks logical that LostFocus() should get called before any other changes are done.(In my situation the selectionchange resets the LineEdit before I could save the data.)

I will look up the source later (for now a mousehook will do it) and check if I could change it for ArrayCtrl. Or are there points against this?

greetings and happy xmas

Yeah. I am getting better. Very Happy

This one should fix it. But please have a look on it.

void ArrayCtrl::DoPoint(Point p, bool dosel) {
	if(!HasFocusDeep())
		SetWantFocus();
	
	p.y += sb;
	if(p.y >= GetTotalCy() && IsAppendLine())
		KillCursor();
	clickpos.y = GetLineAt(p.y);
	if(!IsNull(clickpos.y))
		SetCursor0(clickpos.y, dosel);
	else
	if(IsCursor())
		AcceptRow();
}

Tomorrow I will check the one when in RowEdit-Mode.

Well, you are right that the behaviour should be consistent.

The problem is that SetWantFocus was moved from the place you suggest to the end of DoPoint in 2005.

The motivation in ArrayCtrl is that sometimes you want to know the previous focus placement when doing WhenSel.

Therefore, maybe, we should rather fix TreeCtrl(?)

This shows me that thinking twice is better...
I agree. It's better to have the option to find out the previous focus. For my problem mouse- and keyhook will work.

I will check the TreeCtrl next weekend.
