I have a TGListTree and I implemented some kind of lazy loading of its content. Whenever a folder is opened, I add the children items to it.
My problem is that I need to know when a folder in the tree is opened by the user. I have used the DoubleClicked signal until now and it works great as long as the user doesn’t simply click on the + next to the folder icon…
Did I miss an obvious way of getting a signal for folders opening ?
Thanks in advance,
