Previously, when a sheet was resized, there were a number of problems:
- Sheets in Cocoa resize their width symmetrically, such that they always remain centered. This was not happening in Cappuccino.
- When a sheet is resized wider than its parent window, the shadow at the top of the sheet was growing wider than the bounds of the parent window's title bar, which makes no sense since the shadow is supposed to be cast by the title bar.
- Sheets had no top border, so when they were resized wider than the parent window, the top edge looked like it was cut off. In Cocoa, sheets have a top border that sits under the title bar of the parent window, and which is visible when the sheet is resized wider than the parent window.
This commit addresses these problems as follows:
- Sheet width is now resized symmetrically.
- Sheet resizing is pinned to the screen bounds.
- The top sheet shadow is pinned to the width of the parent window's content view.
- Sheets now have a top border.
In addition to these changes, a redundant sheet top shadow was eliminated from one of the _CPWindowView subclasses.
Fixes#1846
Previously, the content view of almost all window types
could overlap the frame of the window.
This is a follow on to b28429f which insets the content view
from the frame for all relevant window types.
Refs #1798
Previously, windows with no minimum size could be resized
by the user such that the content view was completely hidden, and then
resized such that the window was effectively turned inside out.
This obviously needed to be fixed.
Now, when the user resizes a window, each _CPWindowView subclass
is asked for the minimum resize size, with the size being additively
set by each subclass. This minimum size takes into account things
like the title bar, divider line, and close button, and always leaves
at least 2px height for the content view.
The user-requested size is then pinned to the minimum resize size.
In the process of fixing this bug, I discovered in the Cocoa docs
that the CPWindow -setFrame: methods should ignore minSize and maxSize.
Other changes:
- Take the divider height into account in contentRectForFrameRect for titled windows.
- Use _CG macros and fix formatting.
Closes#1753
