painting problem.

[joseph]

Hi

I have a QRubberBand. Actually its says that QRubberBand will re-paint the "Parent object" while moving the Rubberband on its parent .( IF i am wron please correct me ..)

BUT.....
How can i restrict a QRubberband from re-painting its parent.
At the same time i want have to pass the "Parent object " in QRubberBand.
Is there any setFunction() to make it possible.

Thank you

I am working with a Drawing application on a canvas ( Q3Frame ).
On canvas i will draw images. The folowing senario comes while CUT and PASTE the images in canvas.

While CUT : ( using CTRL + X )
1) i used to hide the images in canvas using BACKGROUND colour of canvs.
2) Then enduser wil get a feeling that the images have been cut from the canvas.


While PASTE : ( Using CTRl + V )
1) Now a QRubberband band wil comes along with a special cursor. 2) User can move this QRubberBand over the canvas , for locate the PASTING.
3) while clicking Left-mouse-button ...
a) the images will be pasted in canvas
b) and QRubberBand will be disappered

Exact Problem:
1) After CTRL + X , the images will be hidden in QFrame ( Drawing Canvas ).
2) Then user press CTRL +V for pasting , then rubberBand will comes .
3) While moving the rubberband over the hidden images in canves , they gets painted.
i want to avoid this re-painting of hidden images in canvas.


please help me.
thanks

But this is your implementation's fault.
Post some code, maybe we can help you.

How do you exactly hide those images? I suggest removing them entirely from the canvas.

Anyway, may I suggest to switch to QGraphicsView? You are using deprecated functionality.
