QListWidget which signal?

[SPlatten]

I am using QListWidget, the height of the control displays one item, I want to use a signal that is emitted when the selection is changed to another, I started using itemEntered, this is emitted the instant the mouse moves into the control. I tried itemSelectionChanged, I thought this would be the one to use but it does not get emitted when the selection is changed, I've tried various other signals and I can't find one that is emitted when I change the selection.

Is there anything else required to enable this?

[SPlatten]

Ok, in doing this I found the problem, my slot was expecting the selected item to be in the response, it isn't, the signal is being emitted and the slot was being called but due to a bug in the slot it wasn't doing what I wanted....I will sort it out now.

@SPlatten
So far as I know QListWidget::itemSelectionChanged should be fired when changing which item is selected, and other examples on the web show people using it. You sure about your test code?

@SPlatten Please show your code where you're using itemSelectionChanged, especially the connect call and slot signature.

I connect all the signals available to a slot I call a repeater as this then emits another signal which has all the data from the original signal and identifies the signal and slot it is coming from.

@SPlatten
I suggest you try something which is less than 100-odd lines of code. A minimal piece of code if you wish others to examine it.

[SPlatten]

@JonB , fair enough, I'll knock up a demo.

[SPlatten]

Ok, in doing this I found the problem, my slot was expecting the selected item to be in the response, it isn't, the signal is being emitted and the slot was being called but due to a bug in the slot it wasn't doing what I wanted....I will sort it out now.

[JonB]

@SPlatten
...which is why I suggested knocking up a small demo for these sorts of "inexplicable" issues before posting, always... :) Plus, always put a qDebug() into slots to see if they are actually called, not rely on some behaviour you expect to be performed.

[ollarch]

@SPlatten Do you use a debugger? Setting debug points on the connections and the slots you will have found the bug yourself. Also look at the console output as Qt libs write output there.

@JonB

From my experience I can say, you can solve some of your problems on your own, when trying to explain them (and your code) to others. A couple of times, I was about to post something here, because I couldn't find any solution for my issue... then, while I wrote the topic and tried to eplain my issue, things became clear and the problem got resolved in like 5mins.
These "Oh-gosh-I-am-such-an-idiot-Moments"... ;-)

@Pl45m4 Its called Rubber Duck Debugging
🤓

[SPlatten]

What can I say I'm doing lots of things at the same time, so I missed something, not the end of the world.
