This reverts commit adc63cecb1.
Reverting this commit is only a temporary measure to facilitate a stable
release of JUCE 8. Further work on this feature will continue on
develop, and will likely be included in a future release of JUCE 8.
Resizing using window manager functionality (e.g. clicking and dragging
in the non-client area) will send WM_SIZING to the window, which in turn
will enable continuous repainting in the D2D renderer until the resize
operation ends.
Continuous repainting is required in order for the window to display
correctly during the resize. Without continuous repainting, some frames
may not be completely painted, and may display with black areas,
producing a flickery effect.
When a resize is controlled entirely by the client, e.g. using the
corner resizer in the AudioPluginDemo standalone, WM_SIZING is never
posted. Instead, we assume that if the window has captured the cursor
during a setBounds call then it is probably resizing. We enable
continuous repainting in this case, and stop repainting once the window
releases the mouse.
An alternative appropach would be to add some kind of start/stop resize
API to ComponentPeer. I'm currently reluctant to do that because the
ComponentPeer API is already so large.
This patch should resolve an issue introduced in
0ab30555fc where arrow keys and other
directional keys (home, end, page up, page down) stopped working as
expected.
With this patch in place,
- IME input in plugins should work correctly, including for languages
with a selection palette (Japanese) and languages where multiple
keypresses combine to a single character (Korean).
- Keyboard shortcuts should work (cut, copy, paste)
- Directional keys should work
