Help coding raygui.h wrapper file

jay · 7 March 2025 22:07

Hi folks.
I was trying to port a raylib c example to odin and I found that the GuiValueBoxFloat proc is missing in the raygui.odin file. I’m hoping someone that knows how will help me add it to odin. I’m a newbe to both programming and Odin I don’t know how to do it.

Here is the raygui.h function that it wraps.

RAYGUIAPI int GuiValueBoxFloat(Rectangle bounds, const char *text, char *textValue, float *value, bool editMode); // Value box control for float values

Thanks in advance to any help received.

My recommendation would be to look at the source for raygui.odin and look at how GuiValueBox (the integer version) is bound. It should be fairly easy to copy-paste-modify that existing binding for GuiValueBoxFloat.

Thanks for the reply. Yes but it’s more involved than I know how to deal with. Here are some of the things from ComboBox.
// ComboBox
GuiComboBoxProperty :: enum c.int {
COMBO_BUTTON_WIDTH = 16, // ComboBox right button width
COMBO_BUTTON_SPACING, // ComboBox button separation
}
There is also an enum: // Gui controls
and more. I was hoping someone who knows more than me would tackle the job.
