IMContextSimple

GtkIMContextSimple is a simple input method context supporting table-based input methods. It has a built-in table of compose sequences that is derived from the X11 Compose files.

GtkIMContextSimple reads additional compose sequences from the first of the following files that is found: ~/.config/gtk-3.0/Compose, ~/.XCompose, /usr/share/X11/locale/$locale/Compose (for locales that have a nontrivial Compose file). The syntax of these files is described in the Compose(5) manual page.

Unicode characters

GtkIMContextSimple also supports numeric entry of Unicode characters by typing Ctrl-Shift-u, followed by a hexadecimal Unicode codepoint. For example, Ctrl-Shift-u 1 2 3 Enter yields U+0123 LATIN SMALL LETTER G WITH CEDILLA, i.e. ģ.

Emoji

GtkIMContextSimple also supports entry of Emoji by their name. This works by first typing Ctrl-Shift-e, followed by an Emoji name.

The following names are supported: - :-) 🙂 - 8-) 😍 - <3 ❤ - kiss 💋 - grin 😁 - joy 😂 - :-* 😚 - xD 😆 - like 👍 - dislike 👎 - up 👆 - v ✌ - ok 👌 - B-) 😎 - ;-) 😉 - ;-P 😜 - :-p 😋 - 3( 😔 - :-( 😞 - :] 😏 - :'( 😢 - :_( 😭 - :(( 😩 - :o 😨 - :| 😐 - 3-) 😌 - >( 😠 - >(( 😡 - O:) 😇 - ;o 😰 - 8| 😳 - 8o 😲 - :X 😷 - }:) 😈

Functions

addComposeFile void addComposeFile(string composeFile)
addTable void addTable(ushort[] data, int maxSeqLen, int nSeqs): Adds an additional table to search to the input context. Each row of the table consists of @max_seq_len key symbols followed by two #guint16 interpreted as the high and low words of a #gunicode value. Tables are searched starting from the last added.
getIMContextSimpleStruct GtkIMContextSimple* getIMContextSimpleStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*

From IMContext

gtkIMContext GtkIMContext* gtkIMContext;: the main Gtk struct
getIMContextStruct GtkIMContext* getIMContextStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
deleteSurrounding bool deleteSurrounding(int offset, int nChars): Asks the widget that the input context is attached to to delete characters around the cursor position by emitting the GtkIMContext::delete_surrounding signal. Note that @offset and @n_chars are in characters not in bytes which differs from the usage other places in #GtkIMContext.
filterKeypress bool filterKeypress(GdkEventKey* event): Allow an input method to internally handle key press and release events. If this function returns %TRUE, then no further processing should be done for this key event.
focusIn void focusIn(): Notify the input method that the widget to which this input context corresponds has gained focus. The input method may, for example, change the displayed feedback to reflect this change.
focusOut void focusOut(): Notify the input method that the widget to which this input context corresponds has lost focus. The input method may, for example, change the displayed feedback or reset the contexts state to reflect this change.
getPreeditString void getPreeditString(string str, PgAttributeList attrs, int cursorPos): Retrieve the current preedit string for the input context, and a list of attributes to apply to the string. This string should be displayed inserted at the insertion point.
getSurrounding bool getSurrounding(string text, int cursorIndex): Retrieves context around the insertion point. Input methods typically want context in order to constrain input text based on existing text; this is important for languages such as Thai where only some sequences of characters are allowed.
reset void reset(): Notify the input method that a change such as a change in cursor position has been made. This will typically cause the input method to clear the preedit state.
setClientWindow void setClientWindow(Window window): Set the client window for the input context; this is the #GdkWindow in which the input appears. This window is used in order to correctly position status windows, and may also be used for purposes internal to the input method.
setCursorLocation void setCursorLocation(GdkRectangle* area): Notify the input method that a change in cursor position has been made. The location is relative to the client window.
setSurrounding void setSurrounding(string text, int len, int cursorIndex): Sets surrounding context around the insertion point and preedit string. This function is expected to be called in response to the GtkIMContext::retrieve_surrounding signal, and will likely have no effect if called at other times.
setUsePreedit void setUsePreedit(bool usePreedit): Sets whether the IM context should use the preedit string to display feedback. If @use_preedit is FALSE (default is TRUE), then the IM context may use some other method to display feedback, such as displaying it in a child of the root window.
addOnCommit gulong addOnCommit(void delegate(string, IMContext) dlg, ConnectFlags connectFlags): The ::commit signal is emitted when a complete input sequence has been entered by the user. This can be a single character immediately after a key press or the final result of preediting.
addOnDeleteSurrounding gulong addOnDeleteSurrounding(bool delegate(int, int, IMContext) dlg, ConnectFlags connectFlags): The ::delete-surrounding signal is emitted when the input method needs to delete all or part of the context surrounding the cursor.
addOnPreeditChanged gulong addOnPreeditChanged(void delegate(IMContext) dlg, ConnectFlags connectFlags): The ::preedit-changed signal is emitted whenever the preedit sequence currently being entered has changed. It is also emitted at the end of a preedit sequence, in which case gtk_im_context_get_preedit_string() returns the empty string.
addOnPreeditEnd gulong addOnPreeditEnd(void delegate(IMContext) dlg, ConnectFlags connectFlags): The ::preedit-end signal is emitted when a preediting sequence has been completed or canceled.
addOnPreeditStart gulong addOnPreeditStart(void delegate(IMContext) dlg, ConnectFlags connectFlags): The ::preedit-start signal is emitted when a new preediting sequence starts.
addOnRetrieveSurrounding gulong addOnRetrieveSurrounding(bool delegate(IMContext) dlg, ConnectFlags connectFlags): The ::retrieve-surrounding signal is emitted when the input method requires the context surrounding the cursor. The callback should set the input method surrounding context by calling the gtk_im_context_set_surrounding() method.
