Yes, we understood the problem. Here's a couple of pseudo algorithms to solve it. The choice is yours:

mousePressEvent:
    pressPoint = mouse press event's position
 
contextMenuEvent:
    if distance between context menu event's position and pressPoint is less than something
        show context menu
    else do nothing

mousePressEvent:
    pressPoint = mouse press event's position

contextMenuEvent:
    if distance between context menu event's position and pressPoint is less than something
        show context menu
    else do nothing

or

mousePressEvent:
    pressPoint = mouse press event's position
 
mouseReleaseEvent:
    if distance between mouse release event's position and pressPoint is less than something
        showContextMenu = true
    else
        showContextMenu = false
 
contextMenuEvent:
    if showContextMenu
        show context menu
    else do nothing

mousePressEvent:
    pressPoint = mouse press event's position

mouseReleaseEvent:
    if distance between mouse release event's position and pressPoint is less than something
        showContextMenu = true
    else
        showContextMenu = false

contextMenuEvent:
    if showContextMenu
        show context menu
    else do nothing

or

mousePressEvent:
    showContextMenu = true
 
mouseMoveEvent:
    showContextMenu = false
 
contextMenuEvent:
    if showContextMenu
        show context menu
    else do nothing

mousePressEvent:
    showContextMenu = true

mouseMoveEvent:
    showContextMenu = false

contextMenuEvent:
    if showContextMenu
        show context menu
    else do nothing

Hmm... could you provide a minimal compilable example which reproduces the problem? Because as for now we're talking about a bit abstract behaviour.

[mickey]

i think so long...but Do I have use some flag to do this?when right mouse button do some things (translate, change color of scene where I pick (only if I have a pushbutton down). so if traslate or changing color (it works), when I releae mouse appear menu; I can follow advice of jpn (for every things I set a flags menuContext=false), but I hoped find a Qt way....such as ignore() (but I haven't idea how use it):..

[wysota]

If you do, remember to reimplement also the release event to clear values which were set in previous handlers.

I'm trying this; with mouseMoving flag it works; but I wonder how use ignore() function

void MyWidget::contextMenuEvent(QContextMenuEvent* e) {
	if (mouseMoving) {mouseMoving = false; return;}
         //if (mouseMoving)     e->ignore(); //Must I use ignore() in that way?

void MyWidget::contextMenuEvent(QContextMenuEvent* e) {
	if (mouseMoving) {mouseMoving = false; return;}
         //if (mouseMoving)     e->ignore(); //Must I use ignore() in that way?

Where do I have to use ignore? and how cal it? thanks
