It is now possible to control button click behavior to trigger either
on button pressed or button released. By default nuklear now used
on button pressed but `#define NK_BUTTON_TRIGGER_ON_RELEASE` lets
you change button behavior to trigger on release. I furthermore
enhanced slider dragging behavior to not force you to hover the
slider at all times.
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.
All modifed state changed by the demo rendering functions is now set
to default values after being called. I tried to save and restore all
relavent state but for some reason function glBlendEquationSeperate
is not defined for me. So I decided to make it as easy as possible
for me and just set everything to default. This means you have to
either save and restore or reset your own OpenGL state after calling
`nk_xxx_render`. I know it is not perfect but I have no better
solution at this point in time.
Editfield width inside properties were previously calculate by text
length + padding and always the size of the edit cursor, even in case
were no one is editing the property. Now the cursor size is only
added while editing.
Text manipulation in SDL1.2 is quite a pain to say the least. But
since this demo is already quite limited in some aspects I think it
is fine to just get things running. That being said if used seriously
then text input still needs some work.
I personally do not have a retina display, but I added some changes
to all `GLFW` demos/examples. If there are still issues please
report back to me what is not working correct (please test out clipping
by playing around with scrollbars as well)
Fixed a small copy & paste error which pushes the wrong texture
into an empty draw list. In normal cases this never occurs but is
still a big if used independent of libraries use cases.
`nk_tree__push` was not supposed to be seen as private but more like
the more extended way of handling duplicate tree elements. But I used
double underscore which is the general indicator for private. I renamed
it know to nk_tree_push_id, to hopefully make it clearer.
This commit fixes a bug that occurs if you move the cursor inside
text and then back to the end of the text and insert a character.
Caused was the bug by an incorrect check if the cursor is at the
end of the string.
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.
