Mouse events in Qt
-
1 down vote favorite
1I have 3 events defined as follows:
@void mouseMoveEvent(QMouseEvent *eventMove);
void mousePressEvent(QMouseEvent *eventPress);
void mouseReleaseEvent(QMouseEvent *releaseEvent);@Now, let's say I want to do something when the mouse is clicked and moved until the mouse is released. e.g. Give an output ! until the conditions described upper are true.
I have tried to set a global variable let's say @bool a @
and make it @true@
in
@mousePressEvent(...)@and
@false@in
@mouseReleaseEvent(...)@
but when in
@mouseMoveEvent(...)@
the
@a@
is always @true@, even when button is released.

Widgets only receive mouse move events when they have received a press but not yet a release event before, i.e. when the mouse is dragging. This is unless the mouse tracking property (setMouseTracking) is enabled. That's why you always see the variable being true.

Any solution for that?

Well yes, enable mouse tracking o_O
