If you want to input Japanese/Chinese/Korean in the text input widget:
|
||||
|
||||
- when loading the font, pass a range that contains the characters you need, e.g.: io.Fonts->GetGlyphRangesJapanese()
|
||||
- to have the Microsoft IME cursor appears at the right location in the screen, setup a handler for the io.ImeSetInputScreenPosFn function:
|
||||
|
||||
#include <Windows.h>
|
||||
#include <Imm.h>
|
||||
static void ImImpl_ImeSetInputScreenPosFn(int x, int y)

io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application
|
||||
|
||||
- tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
|
||||
- tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
