disabling highlight effect for qlistwidget items

[sushmacr]

Hi All,

I am developing a screen which is a list of thumbnails. I am using a qlistwidget and for each item in the list a qframe is set with setItemWidget(). I am able to render the image in the QFrame of the list item but on selecting the list item the row including the qframe gets highlighted. The highlighting effect is causing a repaint and the image in the thumbnail gets painted with the highlight color. Is there any way to restrict the area of selection for listwidgetitem? or disable single click for listitem? or disable highlight effect on listitem selection?

Why do you use a QListWIdget at all when you just want to show some widget one above each other? Why not a QScrollView with a QVBoxLayout? Your architecture using one widget for each row is doomed to fail performance and resource wise if you intend to use more than say 50 items.

its thumbnail with description text so use of qlistwidget is serving the purpose. I have control on the items and the number or rows is atmost max 5 so there is no problem related to resource.....the only issue i am facing is with the highlight.

I'd suggest revising your architecture and use just your own item delegate (which is responsible for example for drawing items - so you can draw thumbnail, description and do not draw highlight).

If you using your own widgets for the items and do not use the functionality provided by QListWidget at all, you can disable selecting in the listview at all and only use it as a layout manager.

Can you suggest what would be best to use in my case? Requirement is a list of thumbnails+text as item. Selection allowed for each such item in list without highlight....

Selection allowed for each such item in list without highlight....
How will you then identify if the item is selected or not ?

In any case, delegates is the proper thing to render items in a custom way.

I meant to say restrict the highlight area (like highlight only text section) so that the image doesnt get painted with highlight color. If this is possible in QListWidget only then my problem is solved or else i need to change to item delegates.

Not possible without delegates as far as I know.
