When use mouse select a line text in the LineEdit,if don't release mouse leftkey and unselect text,it can't unselect line two ends character.This bug is exist for linux and windows.

When use mouse leftkey drag selected text to new place,sometime draged text is to disappear.For LineEdit,if refresh it,dosappear character can reappear.But for CodeEdit,these characters is real lose. This bug is for ubuntu linux.
I fixed them.

I do not see anything wrong. What is "two ends character"? Last two characters of line?

Actually, you have broken MOVE operation here.

Default is to MOVE the text. That involves deleting the source text. If you want to COPY, you have to hold Ctrl key.

No,I don't break move operation.In fact, the operation to remove the select source is by the DoDragAndDrop.In the windows,"if(DoDragAndDrop(ClipFmtsText(), iw) == DND_MOVE) {
RemoveSelection();" appears to be no problems. but for Ubuntu,some time move text may lose.

Thanks, now I can see the problem with first and last characters.

Now fixed:

void LineEdit::MouseMove(Point p, dword flags) {
	if((flags & K_MOUSELEFT) && HasFocus() && HasCapture()) {
		int c = GetMousePos(p);
		PlaceCaret(c, mpos != c);
	}
}

I will check D&D issue soon - but I believe it is rather problem with DnD in X11 in general, so there should go the fix.

Hi,

I believe that the whole issue is in fact visual artifact of Compiz vs used cursor Image (too big).

I have attempted to make it smaller - now artifacts are gone. I hope this will solve this drag&drop issue.

Well, I have now spend 5 minutes moving the text in LineEdit, with no problem detected.

Perhaps you could post youtube video or something? I guess it must be some very slight difference about how we are doing that...

Do you push any keys? Or just plain simple select - drag - drop?

What is the shape of cursor before drag?
