Drag Drop Images from WebPage into QTextEdit

[Nemo]

Hi guys,

Does QTextEdit have support for images copied from Web ? I mean when a user cut/copies/pastes data from the Web, I end up with place holders in my richtextbox editor which I have derived from QTextEdit. I tried overwriting canInsertfromMimeData and insertFromMimeData, the code segment for source->hasImage() does not execute. I even used the source->hasHtml() this seems to work fine but yet no Images. Any help will be appreciated. Thanks in advance!!

subclass QTextEdit insertFromMimedata or so ...

here a sample ....

To copy to clipboard, switch view to plain text mode

Did you mean [WIKI]Drop files and images on QTextEdit[/WIKI]?

[wysota]

Eeem.... yeah, I think I did

[Nemo]

Yeah!! I had checked that out before, no go! See I will explain what is happening. When I dragging just text there is not issue, Just dragging images no text it okay. Only when I just Ctrl + A or Just select Text and Pics together thats when I hit the problem. Now I have an idea what to do ...if I can get just get the <img> tags and then download the images to a temp location and then changes the src of the <img> to these images I will be okay. But the issue how do I get the <img> tags, you like an html editor without having to parse ( find replace ? ) the html. ( yeah, yeah ...I am lazy)

Hello All,
I am new to Qt. In my project, I am also coming up with same issue. I will want to copy contents (contents include text, images combined) from a web page or any external source and paste in my qtextedit. But, images are not getting displayed and only the text gets pasted. If I copy images alone and try to paste, it is displayed in qtextedit . If I am correct, the issue is related to collecting mimedata. When I copy image alone, mimedata format is stored as Image. But it doesn't work when trying to copy text and image together. I wish that someone will help me to resolve this issue.

Thanks
Viswanathan
