Frequently Asked Question
|
||||
-------------------------
|
||||
<b>How do you use ImGui on a platform that may not have a mouse and keyboard?</b>
|
||||
|
||||
I recommend using [Synergy](http://synergy-project.org) and the uSynergy.c micro client to share your mouse and keyboard. This way you can seemingly use your PC input devices on a video game console or a tablet. ImGui was also designed to function with touch inputs if you increase the padding of widgets to compensate for the lack of precision of touch devices, but it is recommended you use a mouse to allow optimising for screen real-estate.
|
||||
|
||||
<b>I integrated ImGui in my engine and the text or lines are blurry..</b>
|
||||
|
||||
- Try adjusting ImGui::GetIO().PixelCenterOffset to 0.0f or 0.5f.
|
||||
- In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f).
|
||||
|
||||
<b>Can you create elaborate/serious tools with ImGui?</b>
|
||||
|
||||
Yes. I have written data browsers, debuggers, profilers and all sort of non-trivial tools with the library. There's no reason you cannot, and in my experience the simplicity of the API is very empowering. However note that ImGui is programmer centric and the immediate-mode GUI paradigm might requires a bit of adaptation before you can realize its full potential.
|
||||
|
||||
<b>Can you reskin the look of ImGui?</b>
|
||||
|
||||
Yes, you can alter the look of the interface to some degree: changing colors, sizes and padding, font. However, as ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. The example below uses modified settings to create a more compact UI with different colors:

Extra fonts for ImGui.
|
||||
THOSE FONTS ARE OPTIONAL.
|
||||
|
||||
ImGui embeds a copy of 'proggy_clean' that you can use without any external files.
|
||||
Export your own font with bmfont (www.angelcode.com/products/bmfont).
|
||||
|
||||
bmfont reads fonts (.ttf, .fon, etc.) and output a .fnt file and a texture file, e.g:
|
||||
|
||||
proggy_clean.fon --> [bmfont] ---> proggy_clean_13.fnt
|
||||
proggy_clean_13.png
|
||||
|
||||
Configure bmfont:
|
||||
|
||||
- Export .fnt as Binary
|
||||
- Tip: uncheck "Render from TrueType outline" and "Font Smoothing" for best result with non-anti-aliased type fonts.
|
||||
But you can experiment with other settings if you want anti-aliased fonts.
|
||||
|
||||
|
||||
(A) Use font data embedded in ImGui
|
||||
|
||||
// Access embedded font data
|
||||
const void* fnt_data; // pointer to FNT data
|
||||
unsigned fnt_size; // size of FNT data
|
||||
const void* png_data; // pointer to PNG data
|
||||
unsigned int png_size; // size of PNG data
|
||||
ImGui::GetDefaultFontData(&fnt_data, &fnt_size, &png_data, &png_size);
|
||||
|
||||
1. Load the .FNT data from 'fnt_data' (NB: this is done for you by default if you don't do anything)
|
||||
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.Font = new ImBitmapFont();
|
||||
io.Font->LoadFromMemory(fnt_data, fnt_size);
|
||||
|
||||
2. Load the .PNG data from 'png_data' into a texture
|
||||
|
||||
|
||||
|
||||
(B) Use fonts from external files
|
||||
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
|
||||
1. Load the .FNT data, e.g.
|
||||
|
||||
// proggy_clean_13 [default]
|
||||
io.Font->LoadFromFile("proggy_clean_13.fnt");
|
||||
io.FontTexUvForWhite = ImVec2(0.0f/256.0f,0.0f/128);
|
||||
io.FontYOffset = +1;
|
||||
|
||||
// proggy_small_12
|
||||
io.Font = new ImBitmapFont();
|
||||
io.Font->LoadFromFile("proggy_small_12.fnt");
|
||||
io.FontTexUvForWhite = ImVec2(84.0f/256.0f,20.0f/64);
|
||||
io.FontYOffset = +2;
|
||||
|
||||
// proggy_small_14
|
||||
io.Font = new ImBitmapFont();
|
||||
io.Font->LoadFromFile("proggy_small_14.fnt");
|
||||
io.FontTexUvForWhite = ImVec2(84.0f/256.0f,20.0f/64);
|
||||
io.FontYOffset = +3;
|
||||
|
||||
// courier_new_16
|
||||
io.Font->LoadFromFile("courier_new_16.fnt");
|
||||
io.FontTexUvForWhite = ImVec2(1.0f/256.0f,4.0f/128);
|
||||
|
||||
// courier_new_18
|
||||
io.Font->LoadFromFile("courier_new_18.fnt");
|
||||
io.FontTexUvForWhite = ImVec2(4.0f/256.0f,5.0f/256);
|
||||
|
||||
2. Load the matching .PNG data into a texture
