Darwin Cocoa: Tabs don't show pictures
« on: September 06, 2021, 11:34:40 pm »
Hi folks!

I am trying to display pictures on pagecontrol components tabs. I don't succeed it for Darwin, in other OS the pictures are displayed correctly.
It's a bug?

If you look at the Apple Cocoa documentation for NSTabView you will note that there is no facility for including an image in a tab.

trev is right not quite right. 

NSTabViewItem is responsible for the page control tabs. There's a property added for an image... however, it's only available for macOS 10.10 (and was never implemented originally)

It's also need to note, that masOS design guildelines doesn't even mention the possibility of having an image on the tabview.

Instead the use of "label" is encouraged.

Thank you for your answers and patience.  Makos is a completely new system for me.  Therefore, I will always be grateful for additional information.
