Resize image with mouse QTextEdit

[A Former User]

Hello.

i am working on a texteditor and it works fine actually. But i have a problem. I want to resize images for QTextEdit inside a dialog. And this dialog should show the image (which shall be resized) and some lines and rectangles like in Word 2013, when you click on the image, the resize corners comes up. Than you drag and drop with the mouse the size you want to give the image.
And now my question: Is it possible in an not too difficult way ? Some tips or and little exmple would help me a lot!

Thanks to all in advance. It would be cool, if the image shoudn't be saved on the disk and then inserted again. So resize it and the size of the image is changed after accepting the dialog with OK for example.

Thanks

Thanks.
That's what I was searching for...

But I have problems with Implementation. I don't know where and how to do that...

Maybe someone can help me with this or can do that and explain what he did.

Thanks in advance

Hello, did you resolve the problem?

Hi
You do realize its via a dialog? no in place in the textEdit directly.

I don't want to resize it via a dialog. I need to do that with the mouse (manually)
