Signal Details

The “line-mark-activated” signal

void
user_function (GtkSourceView *view,
               GtkTextIter   *iter,
               GdkEvent      *event,
               gpointer       user_data)

Emitted when a line mark has been activated (for instance when there was a button press in the line marks gutter). You can use iter to determine on which line the activation took place.

Parameters

view

the GtkSourceView

 

iter

a GtkTextIter

 

event

the GdkEvent that activated the event

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last


The “move-lines” signal

void
user_function (GtkSourceView *view,
               gboolean       copy,
               gint           count,
               gpointer       user_data)

The ::move-lines signal is a keybinding which gets emitted when the user initiates moving a line. The default binding key is Alt+Up/Down arrow. And moves the currently selected lines, or the current line by count . For the moment, only count of -1 or 1 is valid.

Parameters

view

the GtkSourceView which received the signal

 

copy

TRUE if the line should be copied, FALSE if it should be moved

 

count

the number of lines to move over.

 

user_data

user data set when the signal handler was connected.

 

Flags: Action

Since 2.10


The “redo” signal

void
user_function (GtkSourceView *sourceview,
               gpointer       user_data)

Flags: Action


The “show-completion” signal

void
user_function (GtkSourceView *view,
               gpointer       user_data)

The ::show-completion signal is a keybinding signal which gets emitted when the user initiates a completion in default mode.

Applications should not connect to it, but may emit it with g_signal_emit_by_name if they need to control the default mode completion activation.

Parameters

view

The GtkSourceView who emits the signal

 

user_data

user data set when the signal handler was connected.

 

Flags: Action


The “undo” signal

void
user_function (GtkSourceView *sourceview,
               gpointer       user_data)

Flags: Action
