While a WSClientConnection has a modal window showing, non-modal windows
belonging to that client are not sent any events.
|
|
This patch adds a simple GMessageBox that can run in a nested event loop.
Here's how you use it:
GMessageBox box("Message text here", "Message window title");
int result = box.exec();
The next step is to make the WindowServer respect the modality flag of
these windows and prevent interaction with other windows in the same
process until the modal window has been closed.

This prevents flicker and looks rather good. The main downside is that
resizing gets even more sluggish. That's the price we pay for now.
|
|
To make this feel right, I needed to start passing keyboard modifiers along
with mouse events. That allows shift-clicking to extend the selection. :^)
|
|
On the client side, use GClipboard's data() and set_data(String) to access
the global clipboard. :^)
|
|
This patch adds a GShortcut class. Each GAction can have a GShortcut which
will cause the event loop to listen for that key combination app-globally
and activate the event in case it's pressed.
The shortcut will also be displayed when the action is added to a menu.
Use this to hook up Alt+Up with the "open parent directory" action in the
FileManager app. :^)

This way GWindow doesn't need to do synchronous IPC to fetch the appropriate
size for the window's backing store. This is mostly only relevant during
live resize.
|
|
I'm still feeling this out, but I am starting to like the general idea.
|
|
Use this to implement incremental resizing for Terminal so that we only
ever resize to fit a perfect number of rows and columns.
This is very nice. :^)
|
|
This makes interactive resizing work a lot better, althought it's still not
perfect. There are still glitches and unpleasant flashes of zeroed memory.
|
|
This is pretty limited and not entirely stable, but it does work! :^)
|
|
Windows now learn when the mouse cursor leaves or enters them.
Use this to implement GWidget::{enter,leave}_event() and use that
to implement the CoolBar button effect. :^)

This patch also adds a Format concept to GraphicsBitmap. For now there are
only two formats: RGB32 and RGBA32. Windows with alpha channel have their
backing stores created in the RGBA32 format.
Use this to make Terminal windows semi-transparent for that comfy rice look.
There is one problem here, in that window compositing overdraw incurs
multiple passes of blending of the same pixels. This leads to a mismatch in
opacity which is obviously not good. I will work on this in a later patch.
The alpha blending is currently straight C++. It should be relatively easy
to optimize this using SSE instructions.
For now I'm just happy with the cute effect. :^)

This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)
|
|
And use this to implement shared bitmaps between WindowServer and clients.
