With Qt , text depends on theme (MacOSX in this case)
I did not know this. Very good to know, thank you.
Also , there's no way to change text, only format could be changed.
I didn't know this either. Apparently, Lazarus' Qt interface is hard coded to show the percentage. Fine by me.
I at least figured out how to change the GTK default to match Qt, instead of the goofy default they have set.
I also figured out how to make BarTextFormat settable so you can just load a string into it, but since there's no equivalent for Qt, I decided against doing that.
For some custom progressbar it's best to create your own from TCustomControl or from TGraphicControl (depends on your needs).
Looks like I got me some learnin' to do...

You could try the plShapeProgress component. I believe it is part of the components pack in the CodeTyphon derivative of Lazarus. The default shape is a circle (pie) but you can change it to a vertical bar or a horizontal bar. You can also change the fill colour. See screenshot.
Very nice! Thanks for the tip! Big download for one component

but I'll try it anyway. Maybe I can learn enough from the code to make my own basic progressbar.
