Signals

The default signal is "row-activated", emitted when the user double-clicks a row and also when a row is selected and one of the keys Space, Shift+Space, Return or Enter is pressed.

The "changed" signal is emitted when the selection has changed (please see link about this).

The "cursor-changed" signal is emitted when the position of the cursor (focused cell) has changed.

The "file-changed" signal is emitted if file-monitor is true and the input file being monitored has changed.

The following signals are connected-up for all widgets:

button-press-event, button-release-event, configure-event, enter-notify-event, leave-notify-event, focus-in-event, focus-out-event, hide, show, realize, key-press-event, key-release-event, map-event, unmap-event

Functions

The following functions can be performed upon this widget by any widget capable of emitting signals:

Type Description Parameter Since
enable Sensitise widget Variable name
disable Desensitise widget Variable name
show Show widget Variable name 0.8.1
hide Hide widget Variable name 0.8.1
grabfocus Grab input focus Variable name 0.8.1
refresh Reload input data Variable name
save[2] Save widget data Variable name 0.8.1
clear Remove all widget data Variable name 0.7.21
removeselected Remove selected widget data Variable name

The following general functions can be performed by any widget capable of emitting signals:

Type Description Parameter Since
break Break out of actions list None 0.8.3
command Execute command Shell command
exit Exit dialog A value for the EXIT variable
closewindow Close dialog Variable name
launch Launch dialog Variable name
presentwindow Present dialog Variable name 0.8.1

Conditions

The following conditions can be used within the condition attribute of action directives:

Type Description Argument Since
active_is_true(argument) Active state of toggle widget Variable name 0.8.3
active_is_false(argument) Active state of toggle widget Variable name 0.8.3
command_is_true(argument) Output of shell command Shell command 0.8.3
command_is_false(argument) Output of shell command Shell command 0.8.3
file_is_true(argument) Contents of a file Filename 0.8.3
file_is_false(argument) Contents of a file Filename 0.8.3
sensitive_is_true(argument) Sensitive state of widget Variable name 0.8.3
sensitive_is_false(argument) Sensitive state of widget Variable name 0.8.3
visible_is_true(argument) Visible state of widget Variable name 0.8.3
visible_is_false(argument) Visible state of widget Variable name 0.8.3

true means "true", "yes" or a non-zero value, false means "false", "no" or zero, therefore the shell command is expected to echo one of these values to stdout.

Notes

  1. This widget has a default dimension of 200x100 which can be overridden with the height and/or width directives.

  2. When saving, due to the multiple input data formats, the columns are output in the following raw state: icon-name | stock-id | data0 | data1 | ...
