[Debugger] sometimes opens with locked scrollbars

[diver]

This is hrev44361, gcc2hybrid.

After double clicking a thread in Teams window Debugger sometimes opens in a state where scrollbars are locked. In a different tabs (Images, Breakpoints) scrollbars are ok. Dragging splitters fixes it.

With "locked" you mean disabled, I assume. Which views are affected exactly? The threads list, the central source code view?

[diver]

Yes, they are disabled. Affected views are: Threads tab, Variables tab and StackTraceView. Central source code view is empty so I can't check it.

They visually appear disabled as well? I've occasionally seen similar behavior in other apps where a scrollbar appears "normal", but can't be clicked/dragged on either the arrows or the thumb. This is sometimes accompanied by some slight discoloration on parts of the scrollbar which leads me to suspect that what's going on is overlapping sibling views, but I haven't seen it in a consistent enough manner to analyze it. Also only seen in apps using layout so far for me at least.

[diver]

No, scrollbar appears normal, but they don't react on mouse clicks. I can't see any discoloration, though. I can reproduce it easily in Debugger.

[diver]

Resizing Debugger window a little bit also fixes them.

I can also move scrollbars using keyboard arrows but scrollbars redraw badly.

Changing component to Interface Kit. Sounds like a CLV or scroll bar/view issue. At least to my knowledge Debugger doesn't do anything special with respect to scrolling here.

I wonder if this is a problem with UnarchiveSplitView... diver, can you try commenting out lines 378-388 in src/apps/debugger/user_interface/gui/team_window/TeamWindow.cpp and see if the behavior's still reproducible?

I still can reproduce it with this change.

[diver]

It appears that scrollbar actually reacts on clicks, but I have to click right under the scrollbar, though. Clicking on red area - presses arrow buttons. Clicking on green part - moves knob to the other side.

Fixed in hrev44366.
