84ae4e5880 WindowManager should only flush pixels inside the screen rect. 2019-01-12 16:41:03 +01:00
Andreas Kling
8d78b0a8df Tidy up the h/v line drawing loops a bit. 2019-01-12 16:39:56 +01:00

b4bd4f4b29 Make the Event class virtual. 
I realized that we're leaking all the members in Event subclasses.

8068b8e09e Add a Vector::clear_with_capacity() that doesn't release the backing store. 
Use this for WindowManager's dirty rects to avoid kmalloc traffic.

07873332e7 Coalesce mouse events to make the GUI go fast. 
A simple but effective optimization that avoids tons of redraw. :^)

57b13274da Let the EventLoop drive the WindowManager through WM_Compose events. 2019-01-12 06:47:55 +01:00
Andreas Kling
780e15a6cc All right, let's double buffer the display. It looks so much better. 
This performs like dogshit. I need to make some optimizations. :^)

fd4e86460b Make PS2MouseDevice behave more like a proper character device. 
Get rid of the goofy MouseClient interface and have the GUI event loop just
read mouse data from the character device.

The previous approach was awful as it was sending us into random GUI code
in the mouse interrupt handler.

52e019f9aa Only initiate window title bar drags for left mouse button clicks. 2019-01-12 04:16:40 +01:00

bb28c31531 Get rid of the "root widget" concept in WindowManager. 
Instead just create a GraphicsBitmap wrapper around the display framebuffer
and teach Painter how to draw directly into a GraphicsBitmap.

0e6c19ffa6 Reduce PS2MouseDevice debug spam in every dang mouse interrupt. 2019-01-12 03:20:48 +01:00

5db720dc59 Don't repaint the root layer in invalidated areas with windows over them. 2019-01-12 03:13:42 +01:00

9bc7b128b2 Constrain the mouse cursor to keep it inside the screen rect. 2019-01-12 01:00:24 +01:00

b95aa18315 Hook up the Keyboard device to the AbstractScreen. 
Basic text editing in a TextBox works. How very cool :^)

a3c39ea9d6 Throw up some widgets on screen so we can see what they look like. 2019-01-11 04:10:07 +01:00
Andreas Kling
e5e295052f Hook up the PS2MouseDevice to the AbstractScreen+WindowManager. 
Render the mouse cursor by xor'ing the pixels. I don't know anything about
hardware cursors yet and this way we don't need to recompose the window
hierarchy every time you move the mouse. :^)

31667b47a5 Teach PS2MouseDevice to read the left and right buttons. 2019-01-11 02:45:06 +01:00
Andreas Kling
e740f1195a Add a simple PS/2 mouse device. 
It's not hooked up to anything just yet, but it does read movement deltas.

d1ceb4b603 Fix uninitialized AbstractScreen instance pointer. 
...yeah yeah, one day I'm gonna zero out the kernel's BSS segment. Soon..

f6d2c3ed87 Hook everything up to run the GUI on top of the kernel. 
Okay things kinda sorta work. Both Bochs and QEMU now boot into GUI mode.
There's a ton of stuff that doesn't make sense and so many things to rework.

Still it's quite cool to have made it this far. :^)

4775fd88e3 More window management work. 
- Fix inverted mouse event hit test z-ordering.
- Let the RootWidget backing store simply be the display framebuffer.

659c54e32b Switch into 1024x768x32bpp VESA LFB mode at boot. 
This is going to be pretty cool once I can hook up the Widgets/ code to it.

9963da9005 Start refactoring graphics system to have per-window backing stores. 
It was fun for everyone to share a single framebuffer but it was also
kinda really awful. Let's move towards having a "GraphicsBitmap" as the
backing store for each Window.

This is going to need a lot of refactoring so let's get started.

0d36281162 Refactor FS::find_parent_of_inode() into Inode::parent(). 
This way, Ext2FSInode can cache its parent inode index. This makes absolute
path lookups dramatically faster.
SynthFSInode is also simplified greatly.
