WindowServer was led to believe that the Terminal window had an alpha
channel that had to be respected by the compositor. This caused us to
always consider it as non-opaque when culling dirty rects in compose.
This optimization was broken since who-knows-when. Now we once again do
our best to only repaint the lines that had the "dirty" flag set.
This dramatically reduces the amount of work done by an idle Terminal
since the cursor blinking won't redraw the whole window anymore. :^)
Now that we're bringing back the in-kernel virtual console, we should
move towards having a single implementation of terminal emulation.
This patch rips out the emulation code from the Terminal application
and turns it into the beginnings of LibVT.
The basic design idea is that users of VT::Terminal will implement and
provide a VT::TerminalClient subclass to handle presentation-specific
things. We'll need to iterate on this, but it's a start. :^)
GWindow::~GWindow() deletes the main widget, assuming it was
allocated with new; this is what all other applications do,
so heap-allocate the terminal widget as well even though it's
not necessary in this case.
This was really straightforward since all the necessary pieces were
already in place. This patch just passes a bold font to draw_glyphs()
for buffer cells with the bold attribute set. :^)
This API was returning a "const char*" and it was unclear who took care
of the underlying memory. Returning a String makes that obvious.
Also make sure we close the /etc/passwd file when we're done with it.
Now that we support more than 2 clients per shared buffer, we can use them
for window icons. I didn't do that previously since it would have made the
Taskbar process unable to access the icons.
This opens up some nice possibilities for programmatically generated icons.
This macro goes at the top of every CObject-derived class like so:
class SomeClass : public CObject {
C_OBJECT(SomeClass)
public:
...
At the moment, all it does is create an override for the class_name() getter
but in the future this will be used to automatically insert member functions
into these classes.
This behavior and API was extremely counter-intuitive since our default
behavior was for applications to never exit after you close all of their
windows.
Now that we exit the event loop by default when the very last GWindow is
deleted, we don't have to worry about this.
You now have to pass an Orientation to the GSlider constructor. It's not
possible to change the orientation after construction.
Added some vertical GSliders to the WidgetGallery demo for testing. :^)
Instead of LibGUI and WindowServer building their own copies of the drawing
and graphics code, let's it in a separate LibDraw library.
This avoids building the code twice, and will encourage better separation
of concerns. :^)
Left mouse button selects (and copies the selection on mouse up).
The right mouse button then pastes whatever's on the clipboard. I always
liked this behavior in PuTTY, so now we have it here as well :^)
GWindow::move_to_front() can now be used to move a window to the top of
the window stack.
We use this in Terminal to bring the settings window to the front if it
already exists when it's requested, in case it's hiding behind something.
