Any raygui samples?

[ahungry]

I see the paint program has a Save button, which produces a file on save, and supposedly the library here has support for raygui - I'm new to raylib, raygui, and nim, so hoping to find a good reference to do something simple with the 3.

I found https://github.com/raysan5/raygui/blob/master/examples/custom_file_dialog/custom_file_dialog.c, but when I try guessing at names for the translations based on how raylib did it, I'm hitting some snags (initGuiFileDialog() doesn't exist, at least not when I just import nimraylib_now).

Any help would be greatly appreciated!

I have spent time with it and failed to port this example. The problem is that they use a gui_file_dialog.h module together with the example. And because of the complexity of C file includes it doesn't work when we want to include just a little module in C that uses raygui library.

For reference some files:

custom_file_dialog.nim

gui_file_dialog.nim

```nim from ../../../src/nimraylib_now import Vector2 from os import parentDir, `/` const guiFileDialogHeader = currentSourcePath().parentDir()/"gui_file_dialog.h" {.passC: "-DGUI_FILE_DIALOG_IMPLEMENTATION".} type GuiFileDialogState* {.bycopy.} = object position*: Vector2 size*: Vector2 fileDialogActive*: bool dirPathEditMode*: bool dirPathText*: array[256, char] filesListScrollIndex*: cint filesListEditMode*: bool filesListActive*: cint fileNameEditMode*: bool fileNameText*: array[256, char] selectFilePressed*: bool cancelFilePressed*: bool fileTypeActive*: cint itemFocused*: cint ## Custom state variables (depend on development software) ## NOTE: This variables should be added manually if required dirFiles*: cstringArray dirFilesCount*: cint filterExt*: array[256, char] dirPathTextCopy*: array[256, char] fileNameTextCopy*: array[256, char] prevFilesListActive*: cint proc initGuiFileDialog*(width: cint, height: cint, initPath: cstring, active: bool): GuiFileDialogState {.importc: "InitGuiFileDialog", header: guiFileDialogHeader.} proc guiFileDialog*(state: ptr GuiFileDialogState) {.importc: "GuiFileDialog", header: guiFileDialogHeader.} ```

Now the challenge is to correctly include raygui.h into gui_file_dialog.h so that it works with all the imports. I don't believe it is possible. We kind of have to include that header file into the main compilation target. But we can't do it on-demand since it may require additional #define directives to work properly. I will surrender here.
