Freeze when cancel segmentation

[DA523]

If you cancel segmentation tool (scissors)
CC will freeze only some functions works
but it freezes
You can not close CC etc

CC 2.12 Alpha (windows 10-64 msvc 1916 qt 5.15.2)

I can't reproduce this issue.

Can you on your side? If yes, can you share the file and the exact procedure with us? (admin [at] cloudcompare.org)

[DA523]

1- Left mouse click to select area around vertices
2- Before mouse right click to close selection polygon around vertices, press ESC on keyboard to cancel
then CC will partially freezes and it is reproducible

I've tested with both clouds and meshes and am not able to reproduce, does this always happen with a specific cloud or mesh? If so can you share so we can track down the issue?

[DA523]

It happened with all clouds at least in my PC
an example cloud is attached
please remember to cancel with keyboard ESC before mouse right click

[WargodHernandez]

Ah I was able to reproduce, first test I thought you meant to right click before esc.

I'll look into it.

I'll submit a fix today, just need to add closePolyLine(); to the escape key

Code: Select all

case Qt::Key_Escape:
		closePolyLine();
		cancelButton->click();
		return;

This fixed the issue as far as I can tell.

or just directly release the mouse inside the reset function

Code: Select all

void ccGraphicalSegmentationTool::reset()
{
	if (m_somethingHasChanged)
	{
		for (QSet<ccHObject*>::const_iterator p = m_toSegment.constBegin(); p != m_toSegment.constEnd(); ++p)
		{
			ccHObjectCaster::ToGenericPointCloud(*p)->resetVisibilityArray();
		}

		if (m_associatedWin)
		{
			m_associatedWin->redraw(false);
			m_associatedWin->releaseMouse();
		}
		m_somethingHasChanged = false;
	}

	razButton->setEnabled(false);
	validButton->setEnabled(false);
	validAndDeleteButton->setEnabled(false);
	loadSaveToolButton->setDefaultAction(actionUseExistingPolyline);
}
