This was most notable in the widgets TextBox and TextEditor (and
therefore also ComboBox and ColorInput), because there the cursor
regularly landed just one pixel outside the visible region when
going to the right.
Until now, hidden columns were displayed as visible in the context menu.
An easy way to reproduce this is:
- Open the TextEditor
- Ctrl-O to open the file selector
- Switch to table view
- Right-click the header
Expected behavior:
Hidden columns like 'Owner' and 'Group' should not have a checkmark,
because they are hidden.
Actual behavior: They did have a checkmark. Clicking on it to 'hide'
the already hidden column removed the checkmark, but was a no-op to the
table view.
This commit fixes this behavior, by correctly initializing the context menu,
and properly updating the context menu if external code calls
'set_column_hidden' later.
If a window has child windows when it's destroyed, WindowServer will
now automatically tear down all of its children as well.
This is communicated to the client program through a vector of window
ID's included with the response to WindowServer::DestroyWindow.
This does feel a little bit awkward, but managing it on the client side
also seems a bit awkward.
This is much better than the hack we had of making them Tooltip windows
since frameless windows end up at the right layer in the window stack
automatically, and always get yanked above the parent window simply by
being child windows.
If a window has another window in its Core::Object ancestor chain,
we now communicate that relationship to WindowServer so that it can
act with awareness of parent/child windows.
In TabWidgets with the "uniform tabs" mode on, we will now scale tabs
between a minimum and maximum size, distributing the available space.
Partially addresses #1971.
It's not always safe to access pixel data of a window's backing store
since the kernel may decide to purge it at his leisure. Fix this by
instead picking colors from the color spectrum bitmap directly instead.
Also fix up mouse event logic while we're here so it only cares about
the left mouse button
Fixes#1657.
You can now enter a specific color as #rrggbb instead of clicking your
way through the color picker.
If you still want the color picker, just click the little color rect in
the widget and we'll bring up a ColorPicker. For a visual cue that this
rect is interactive, we use a hover hand cursor when hovering the rect.
When selecting the start of a multi-line line, a selection rect was
displayed for the whole line but the text wasn't rendered properly.
This change prevents the selection rect from being drawn in virtual
lines with no selected characters.
