sokol_clay.h -- drop-in Clay renderer for sokol_gfx.h
|
|
|
|
Do this:
|
|
#define SOKOL_CLAY_IMPL
|
|
|
|
before you include this file in *one* C file to create the
|
|
implementation.
|
|
|
|
Optionally provide the following configuration define both before including the
|
|
the declaration and implementation:
|
|
|
|
SOKOL_CLAY_NO_SOKOL_APP - don't depend on sokol_app.h (see below for details)
|
|
|
|
Include the following headers before sokol_clay.h (both before including
|
|
the declaration and implementation):
|
|
|
|
sokol_gl.h
|
|
sokol_fontstash.h
|
|
sokol_app.h (except SOKOL_CLAY_NO_SOKOL_APP)
|
|
clay.h
|
|
|
|
FEATURE OVERVIEW:
|
|
=================
|
|
sokol_clay.h implements the rendering and event-handling code for Clay
|
|
(https://github.com/nicbarker/clay) on top of sokol_gl.h and (optionally)
|
|
sokol_app.h.
|
|
|
|
Since sokol_fontstash.h already depends on sokol_gl.h, the rendering is
|
|
implemented using sokol_gl calls. (TODO: make fontstash optional?)
|
|
|
|
The sokol_app.h dependency is optional and used for input event handling.
|
|
If you only use sokol_gfx.h but not sokol_app.h in your application,
|
|
define SOKOL_CLAY_NO_SOKOL_APP before including the implementation
|
|
of sokol_clay.h, this will remove any dependency to sokol_app.h, but
|
|
you must call sclay_set_layout_dimensions and handle input yourself.
|
|
|
|
sokol_clay.h is not thread-safe, all calls must be made from the
|
|
same thread where sokol_gfx.h is running.
|
|
|
|
HOWTO:
|
|
======
|
|
|
|
--- To initialize sokol-clay, call sclay_setup(). This can be done
|
|
before or after Clay_Initialize.
|
|
|
|
--- Create an array of sclay_font_t and fill it by calling one of:
|
|
|
|
sclay_font_t sclay_add_font(const char *filename);
|
|
sclay_font_t sclay_add_font_mem(unsigned char *data, int dataLen);
|
|
|
|
The fontId value in Clay corresponds to indices in this array. After calling
|
|
Clay_Initialize but before calling any layout code, do this:
|
|
|
|
Clay_SetMeasureTextFunction(sclay_measure_text, &fonts);
|
|
|
|
where `fonts` is the abovementioned array.
|
|
|
|
--- At the start of a frame, call sclay_new_frame() if you're using sokol_app.h.
|
|
If you're not using sokol_app.h, call:
|
|
|
|
void sclay_set_layout_dimensions(Clay_Dimensions size, float dpi_scale);
|
|
|
|
at the start of the frame (or just when the window is resized.)
|
|
|
|
Either way, do some layout, then at the end of the frame call sclay_render:
|
|
|
|
sg_begin_pass(...)
|
|
// other rendering...
|
|
sclay_render(renderCommands, &fonts);
|
|
// other rendering...
|
|
sgl_draw();
|
|
sg_end_pass();
|
|
sg_commit();
|
|
|
|
One caveat: sclay_render assumes the default gl view matrix, and handles scaling
|
|
automatically. If you've adjusted the view matrix, remember to first call:
|
|
|
|
sgl_matrix_mode_modelview();
|
|
sgl_load_identity();
|
|
|
|
before calling sclay_render.
|
|
|
|
--- if you're using sokol_app.h, from inside the sokol_app.h event callback,
|
|
call:
|
|
|
|
void sclay_handle_event(const sapp_event* ev);
|
|
|
|
Unfortunately Clay does not currently provide feedback on whether a mouse
|
|
click was handled or not.
|
|
|
|
--- if you want to use images with clay, you should pass a pointer to a
|
|
sclay_image to the CLAY macro, like this:
|
|
CLAY({
|
|
...
|
|
.image = { .imageData = &(sclay_image){ .view = view, .sampler = 0 } },
|
|
})
|
|
Using 0 as a sampler uses the sokol default sampler with linear interpolation.
|
|
The image should be created using sg_make_image from sokol_gfx.
|
|
|
|
--- finally, on application shutdown, call
|
|
|
|
sclay_shutdown()
