Kindly help me.

Hi and welcome to devnet,

You have to explain a little bit more of your problem. You are not stating clearly what you want to achieve (for example your title mentions QListView and your text only talks about QLabel and QTextEdit)

Also this the wrong subforum. You seem to have a widget problem not a Qt Quick problem

Thanks ..

My question is i have QtextEdit control and Qlabel.in Qlabel i added one image by using setPixmap function. when i scroll the mouse in Qlabel i want to scroll in Qtextedit control also.

Thanks

Then what do you mean by scroll on the QLabel ? Moving the mouse ? Moving the wheel ?

maxy

Moving the wheel

SGaist

Then you'll have to:

subclass QLabel
add a signal to "propagate" the scrolling value
reimplement wheelEvent and emit the signal from there

Then it's either:
1.

subclass QTextEdit
add a slot to receive the scrolling value and update

have a slot in the "main" widget containing your QLabel and QTextEdit and update the QTextEdit scroll bar from there.

May I know why you want to do it that way ? QTextEdit should already support wheel events

Thanks for your information...

Actually i had an transparent image under that i had text browser .i made all the alignments such that it fits on the transparent area.the text is long than the transparent area ,it is not scrolling to see the rest of the textbrowser,.This is what actual problem

SGaist

In that case, have a look at the doc for Qt::WA_TransparentForMouseEvents

maxy

Thanks,
I already tried this kind of solution but the textbrowser shape is like as rectangle but the image transparent area is like as curve.

SGaist

Then make the QTextEdit a "filter":http://qt-project.org/doc/qt-4.8/qobject.html#installEventFilter for the QLabel event

Thanks for your information.

I fixed the issue!!!!!!!!!!! .

You're welcome,

Don't forget to update the thread's title to solved (also change the subject since it has nothing to do with QListView) so other forum user may know a solution has been found.

maxy

Yes..Sure.Thanks a lot
