Crowded popup menu's missing scroll widgets

[humdinger]

This is hrev52933.

I see this with my rather large font list in Appearance and WonderBrush. The list of fonts is taller than my vertical screen resolution permits and has to be scrolled if you need a font firther down in the alphabet.

If the app window (e.g. Appearance) is near the top of the screen, the widgets are missing at the top and bottom of the font popup meu.
If I move the window down, so the font popup menu is approx. in the lower half of the screen, the widgets appear.

I suppose ​hrev52111 could be the culprit?

Indeed it may be.

Is it fixed in hrev53941?

Nope, still there.

Can you provide screenshot?

Here with the Appearance prefs near the top, scroll arrows are missing:

Here with the Appearance prefs further down, scroll arrows are there:

top: no scrollers

bottom: scrollers

Seems that scrollers are present, but outside of screen. Something wrong with BMenu::_UpdateWindowViewSize or BMenu::_CalcFrame.

I am recently working on menus, so I can take this ticket.

Cool! Weird that it depends on where the pop-up menu is opened. If it's near the top of the screen, the arrows ar emissing, when it's further down they are there...

I have managed to reproduce this bug. It only appears with BMenuField when non-first item is selected (BMenuField attempts to show selected item at same position as menu field). Scrollers are not appear and bottom side of menu is outside of screen.

strange that it does not work with the arrow keys either...
