Hi Frank,
A MouseArea that is not "effectively" visible doesn't receive mouse events --
because testrma is a child of testr it won't receive mouse events when testr
isn't visible. If you instead make those two items siblings (don't forget to
change anchors.fill: parent to anchors.fill: testr), it should work as you were
intending.
Regards,
Michael

Hi,
What I wan to do is:
1. click the background, show the rectangle, move mouse into the rectangle and
hide the rectangle, move the mouse away
2. click the background again, show the rectangle again...
But I get some problems, only the first time is right, and the followed are not
right.
I draw a rectangle, and set MouseArea in it, and I want to get onEntered
message each time I move mouse into it.
But it seams that if I hide the rectangle when the mouse is in it, and move
mouse away, and move mouse into the area again, I will not receive the
onEntered message.
Maybe this is because onEntered and onExited message must be sent in pairs? But
I have reset 'enable' and 'hoverEnalbed' properties of the MouseArea. Can I
reset the mouse enter and exist status, so that I can get mouse enter message
each time?
Below is code. Thanks very much.
yours,
Frank
