I passed a depth value inside `nk_xsurf_resize` and changed it to
default value. I tested it by removing the resizing code and it
worked for me again. Hopefully this fixes the bug.
Some minor issues: an unused variable, fixed a comparison of int against
float, and a pragma warning (pop) that didn't have a matching pragma
warning (push). Potentially more serious was a possible buffer overrun,
where a pointer was being tested against a null terminator, instead of
the char it points to.
There were a few casts from void * missing causing problems when
compiling as C++, also the assert function from <assert.h> was being
used instead of NK_ASSERT(...) in one place.
Fixed window movement for windows without header and some small
wrong calculation inside the panel layout code. In addition I
added another example implementing a simple calculator.
This is the first release version of nuklear (previously: zahnrad).
As for those who no the old version will notice: a lot has changed.
Most obvious should be the two biggest changes. First the name change
because I got critique that the name is hard to comprehend and
remember (understandable for non-germans) and the second is the
transistion from four files (zahnrad.h, zahnrad.c, stb_truetype
and stb_rect_pack) to one single header library file nuklear.h.
I am not 100% convinced that using a single header library is the
right choice here but so far I haven't encountered any problems.
Noticable should be as well that nuklear now directly embeds three
stb libraries: stb_truetype, stb_rect_pack and stb_textedit. Like
in previous versions the first two are optional and the library
can be compiled without. stb_textedit on the other hand powers
the text edit implementation for single as well as multiline
text manipulation. The text edit implementation is still relative
new and untested so you can expect some bugs I have not found yet.
In the demo department a lot changed as well. All platform demos
now don't compile one big demo but instead contain a simple
demo and small abstraction layer over the platform. Main benefit is
better understandablity improved ease of use. The old demo
is now split up and transfered into the example folder while each part
is self contained and compileable. (All examples use glfw I don't now
if this is the best platform but it is at least the simplest.
I also removed the apple demo because I don't have an apple system
and cannot make sure the new version runs with the old version.
Finally a lot of small bugs have been fixed as well as bugs found by
clang analyzer and coverity.
Previously all window, popup, comboboxes, tooltips, menu and
contextuals had a fixed border width of 1 and had the same color.
Now it is possible to change the individual border width and color of
each one seperatly.
This commit extends the optional currently existing low level font
baking API with another more high level font atlas API.
The font atlas takes away some fine grained memory control from the
user but is easier to use and to understand than the lower level API.
I added combined with the font atlas a optional default font which
allows running the library without a user provided truetype font.
While user friendly it is quite big (~12kb) so I added a compiler flag
to remove it from the library while compiling if not wanted.
Finally I added some additional compiler flags to allow easier to use
APIs. The downside is that all of them require the standard library,
so if you don't want to add the standard C library I would recommend
deactivating all flags marked as standard library flags.
Previous visual changes in the library were quite limited with some
colors and some global properties. This commit changes all that and
provides way more control over every widgets visual appearance.
Changes include extended color selection, per widget properties and
the possibility to use skinning.
While the new API allows for a lot more control it is currently quite
low level and needs a lot more testing and probably another higher
level style API to make changes in code easier. I also had to remove
the style modification code inside the demo and will probably first
try to write another higher level API before adding it back in.
This commit also include some breaking changes to existing code like
the missing style stack API and some widget names changes due to
added granularity granted by the rewritten style.
Defining compile flag ZR_COMPILE_WIDTH_VERTEX_BUFFER with 0 would
cause compiler errors. This is now fixed and every compile flag
combination should now work as intended.
The default draw command buffering API now supports filled and
outlined shapes as well as two additional commands: polygon and
polyline. While zahnrad only requires a small number of basic
filled draw command shapes to actual function the underlying canvas
to convert from draw commands to vertex buffer commands allows
for lot more. So the gap should now be filled and drawing more
complex custom is now a little bit easier. I thought about adding a
path drawing API to the draw command API but decided it is not
worth the hassle, at least for now.
I spend the last week(s) with lot of time thinking about this and I
came to the conclusion that recording it is not really worth doing.
In theory it could be interesting but the truth is I don't want to
do any more complex refactoring anymore and want to have a break
from extending this library. I spend over a year on this and I think
it is time for me to move on to other things. I will continue fixing
errors or adding requested essential smaller features but no
more complex rewrites or risky changes.
This is quite a big commit which adds an experimental text script to
UI bytecode compiler. The compiler is still under heavy development
and can and will be under heavy changes, so use with caution.
In addition I added the old file browser for unix like platforms
back into the demo. At the moment it only supports windows but
the only part of the file browser that is platform dependend
is the directory content loader which should be easy to implement
in other platforms as well.
An additional widget for picking a color was added. Color picker use
the new draw call command multicolor rectangle which is not supported
everywhere. All demos using the optional vertex buffer output can use
the color picker without problems. Other platforms need to support
a drawing function or do not it.
