---------------------------------
|

---------------------------------------
|
||||
|
||||
Using an icon font (such as FontAwesome: http://fontawesome.io) is an easy and practical way to use icons in your ImGui application.
|
||||
A common pattern is to merge the icon font within your main font, so you can refer to the icons directly from your strings without having to change fonts back and forth.
|
||||
To refer to the icon from your C++ code, you can use headers files created by Juliette Foucaut, at https://github.com/juliettef/IconFontCppHeaders
|
||||
See Links below for other icons fonts and related tools.
|
||||
A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without
|
||||
having to change fonts back and forth.
|
||||
|
||||
To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut:
|
||||
https://github.com/juliettef/IconFontCppHeaders
|
||||
|
||||
The C++11 version of those files uses the u8"" utf-8 encoding syntax + \u
|
||||
#define ICON_FA_SEARCH u8"\uf002"
|
||||
The pre-C++11 version has the values directly encoded as utf-8:
|
||||
#define ICON_FA_SEARCH "\xEF\x80\x82"
|
||||
|
||||
Example:
|
||||
|
||||
// Merge icons into default tool font
|
||||
#include "IconsFontAwesome.h"
|
||||
ImGuiIO& io = ImGui::GetIO();
|

FREETYPE RASTERIZER, SMALL FONT SIZES
|
||||
---------------------------------------
|
||||
|
||||
Dear Imgui uses stb_truetype.h to rasterize fonts (with optional oversampling).
|
||||
This technique and implementation are not ideal for fonts rendered at _small sizes_, which may appear a little blurry.
|
||||
There is an implementation of the ImFontAtlas builder using FreeType that you can use:
|
||||
|
||||
https://github.com/ocornut/imgui_club
|
||||
|
||||
FreeType supports auto-hinting which tends to improve the readability of small fonts.
|
||||
Note that this code currently creates textures that are unoptimally too large (could be fixed with some work)
|
||||
|
||||
|
||||
---------------------------------------
|
||||
BUILDING CUSTOM GLYPH RANGES
|
||||
---------------------------------
|
||||
---------------------------------------
|
||||
|
||||
You can use the ImFontAtlas::GlyphRangesBuilder helper to create glyph ranges based on text input.
|
||||
For exemple: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.

REMAPPING CODEPOINTS
|

---------------------------------

|

|

All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese, or CP-1251 for Cyrillic) will NOT work!
|
||||
In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.

- 2017/12/13 (1.53) - marked IsRootWindowFocused() as obsolete in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
|

- marked IsRootWindowOrAnyChildFocused() as obsolete in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
|
||||
- 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
|
||||
- 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
|
||||
- 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
|
||||
- 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
