QT Widget ListView with Custom Designed Items
Hi can i use Widget based List Control with custom layouted/designed items?
Which control should i use, how ill set my custom designed widget to be used as template for list items to appear?
Normally you would use a delegate to draw it as you want it to look
(this is kinda a trick as it only draws as widgets until you edit the row, then its
live widgets. but it has good performance.)
Alternatively for only a FEW items, one can use
(and a ListWidget )
Here we simply put a live widget on top of the row item.
This has bad performance with many items and on small boards/phones.
Alternatively for a few items, you can use
In most cases you will be most happy with a model and a view and a delegate as you can share the model with more views and its fast.
@mrjj Thank you for your reply, i tried to understand stardelegate example but its bit overwhelming for me as a new user.
So my question is Cant we use visual custom widget as a delegate instead of overriding Paint method and design it with pure code?
The setItemWidget can be used to inset a widget ( with subwidgets ) on a item but
its not possible to use as a delegate as such.
This method is very easy but also a bit heavy with many items.
But on a desktop class pc. many items is maybe a thousands.
So if app is not to run on smartphone/ Pi boards then it works pretty ok.
However, the delegate and painting is best in terms of memory use and performance.
