ee347effac AK: Use a single StringBuilder throughout JSON serialization. 2019-06-17 21:36:54 +02:00
Andreas Kling
3b9fcab1af VisualBuilder: Switch to JSON for the form output. 
This makes widgets-within-widgets straightforward instead of confusing.
The UI doesn't actually let you put widgets inside one another just yet,
but at least now the output format won't be a problem. :^)

04a8fc9bd7 AK: Add some classes for JSON encoding. 
This patch adds JsonValue, JsonObject and JsonArray. You can use them to
build up a JsonObject and then serialize it to a string via to_string().

This patch only implements encoding, no decoding yet.

9fa4e779ff LibM: Rewrite trigonometric functions. 
This way they seem to actually work as expected ;)

502c54e39a Add a simple spray fill tool 
Could do with some more tweaking no doubt, and it'd be nice to have a
circular spray, but this is better than nothing.

0db2f3cbe6 LibHTML: Add a Frame class, start fleshing out recursive layout. 
Layout is initiated from Frame::layout(). It makes the document's layout
node as wide as the frame, and then we'll take it from there.

cf17e385b5 PaintBrush: Allow editing palette colors by ctrl-clicking them. 
Maybe the ColorDialog class could be fashioned into something generally
usable in LibGUI, but for now it lives in the PaintBrush app. :^)

01d1aee922 AK: Make RetainPtr and Retained more friendly towards const pointers. 
Also add operator T&'s to Retained since it's nice to be able to pass them
to a function that takes a T&.

Andreas Kling
dcbddb4f8c GraphicsBitmap: Provide templated versions of get_pixel() and set_pixel(). 
If we already know the bitmap format used, we can use these functions to
bypass the format checks and go straight to pixel manipulation.

a8b2b96f38 PaintBrush: Use a Queue<Point> for the flood fill. 2019-06-15 10:39:45 +02:00
Andreas Kling
bfaa74f076 AK/Tests: Test Queue<String> with large number of elements. 2019-06-15 10:39:19 +02:00
Andreas Kling
c699d9d79d AK: Add a simple Queue<T> class. 
The underlying data structure is a singly-linked list of Vector<T>.
We never shift any of the vector contents around, but we batch the memory
allocations into 1000-element segments.
 2019-06-15 10:35:35 +02:00
Andreas Kling
9443957c14 PaintBrush: Speed up the bucket tool with smarter use of Vector. 
Put together a pretty well-performing queue using a Vector and an offset.
By using the new Vector::shift_left(int) instead of Vector::take_first()
we can avoid shifting the vector contents every time and instead only
do it every so often.

Maybe this could be generalized into a separate class, I'm not sure if it's
the best algorithm though, it's just what I came up with right now. :^)

Andreas Kling
e9c021de92 PaintBrush: Implement a naive but working bucket fill tool. 
I've used a SinglyLinkedList<Point> for the flood fill queue, since Vector
was death slow. This could definitely be made faster with a better algorithm
and/or data structure. :^)
 2019-06-14 19:11:22 +02:00

1ec5172ce1 GraphicsBitmap: Add set_pixel(x, y, Color) 
This only works for RGB32 and RGBA32 formats.

56cbe15033 PaintBrush: Factor out the pen tool into an actual PenTool class. 
Also add a Tool base class, and an empty BucketTool subclass which is the
next thing to implement.

d900fe98e2 VM: Remove PhysicalPage::create_eternal(). 
Now that it is possible to create non-eternal non-freeable
pages, PageDirectory can do just that.
 2019-06-14 16:14:49 +02:00
Sergey Bugaev
010314ee66 VM: Make VMObject::create_for_physical_range() create non-freeable pages. 
This method is used in BXVGADevice to create pages for the framebuffer;
we should neither make the PhysicalPage instances eternal, nor hand over
actual physical pages to the memory allocator.
