I simplified a lot of API calls by pulling panel memory management
inside the library. All API calls which previously required a panel
as parameter are now handling their panel themself.
Nuklear now has three different property versions for int, float and
added by this commit a double version. Internally an additional change
happend. Now the type of the property is actually taken into account
and floating pointer errors due to casting are less of an issue.
Previously I packed standard library variable arguments as well as
file operation into one define `NK_INCLUDE_STANDARD_IO`. This caused
some problems and I split the define into two. So if you want the old
behavior you need to define `NK_INCLUDE_STANDARD_IO` as well as
`NK_INCLUDE_STANDARD_VARARGS`. If you only want file operations but
not variable arguments only define `NK_INCLUDE_STANDARD_IO` and
if you only want varargs but not file operations please only define
`NK_INCLUDE_STANDARD_VARARGS`.
I had a long standing bug inside nuklear which prevents you from
swapping out a font while the code is being build. This bug is now
fixed but the fix requires _ALL_ `nk_user_font` data structures
provided by `nk_style_set_font` to be persistent.
Demos for x11 and sdl have been update so that `nk_xxx_handle_event'
return true (1) if the given event was usefull and processed by
nuklear and false (1) if not.
Hopefully fixed selection bug for empty lines and made edit widget
usable while being only partially visible. I also added two addition
modes for a vim like expierence with view, insert and replace mode
instead of default replace mode, but only added the new behavior into
the x11 demo so far.
All platform and renderbackend independent examples are now optional
demos for all platforms in `demo/`. Moving some demos from `example/`
provides an easier way to test GUI concepts for users and simplifies
maintenance.
Previously if you use `nk_edit_string` and use flag
`NK_EDIT_CLIPBOARD`, callbacks were not passed. I only tested it with
`nk_edit_buffer` and set the callbacks directly. This wrong behavior
is now fixed and should work copy & paste should behave correctly.
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.
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.
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.
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.
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.
