@subsection preedit IME Support
All desktop operating systems support IME (Input Method Editor) to input characters
that are not mapped with physical keys. IME have been popular among Eeastern Asian people.
And some operating systems start supporting voice input via IME mechanism.
GLFW provides IME support functions to help
you implement better text input features. You should add suitable visualization code for
preedit text.
IME works in front of actual character input events (@ref input_char).
If your application uses text input and you want to support IME,
you should register preedit callback to receive preedit text before committed.
@code
glfwSetPreeditCallback(window, preedit_callback);
@endcode
The callback function receives chunk of text and focused block information.
@code
static void preedit_callback(GLFWwindow* window, int strLength, unsigned int* string, int blockLength, int* blocks, int focusedBlock) {
}
@endcode
strLength and string parameter reprsent whole preedit text. Each character of the preedit string is a codepoint like @ref input_char.
If you want to type the text "寿司(sushi)", Usually the callback is called several times like the following sequence:
-# key event: s
-# preedit: [string: "ｓ", block: [1], focusedBlock: 0]
-# key event: u
-# preedit: [string: "す", block: [1], focusedBlock: 0]
-# key event: s
-# preedit: [string: "すｓ", block: [2], focusedBlock: 0]
-# key event: h
-# preedit: [string: "すｓｈ", block: [2], focusedBlock: 0]
-# key event: i
-# preedit: [string: "すし", block: [2], focusedBlock: 0]
-# key event: ' '
-# preedit: [string: "寿司", block: [2], focusedBlock: 0]
-# char: '寿'
-# char: '司'
-# preedit: [string: "", block: [], focusedBlock: 0]
If preedit text includes several semantic blocks, preedit callbacks returns several blocks after a space key pressed:
-# preedit: [string: "わたしはすしをたべます", block: [11], focusedBlock: 0]
-# preedit: [string: "私は寿司を食べます", block: [2, 7], focusedBlock: 1]
"blocks" is a list of block length. The above case, it contains the following blocks and second block is focused.
- 私は
- [寿司を食べます]
commited text(passed via regular @ref input_char event), unfocused block, focused block should have different text style.
GLFW provides helper function to teach suitable position of the candidate window to window system.
Window system decides the best position from text cursor geometry (x, y coords and height). You should call this function
in the above preedit text callback function.
@code
glfwSetPreeditCursorPos(window, x, y, h);
glfwGetPreeditCursorPos(window, &x, &y, &h);
@endcode
Sometimes IME task is interrupted by user or application. There are several functions to support these situation.
You can receive notification about IME status change(on/off) by using the following function:
@code
glfwSetIMEStatusCallback(window, imestatus_callback);
@endcode
imestatus_callback has simple sigunature like this:
@code
static void imestatus_callback(GLFWwindow* window) {
}
@endcode
You can implement the code that resets or commits preedit text when IME status is changed and preedit text is not empty.
When the focus is gone from text box, you can use the following functions to reset IME status:
@code
void glfwResetPreeditText(GLFWwindow* window);
void glfwSetIMEStatus(GLFWwindow* window, int active)
int glfwGetIMEStatus(GLFWwindow* window)
@endcode
