typedef tnode< NCWidget * > | self |
Definition at line 37 of file NCItemSelector.h.
|
virtual |
Activate selected item.
Can be used in tests to simulate user input.
Derived classes are required to implement this.
Definition at line 512 of file NCItemSelector.cc.
|
virtual |
Add an item to this widget.
Reimplemented from YSelectionWidget.
Definition at line 188 of file NCItemSelector.cc.
|
protectedpure virtual |
Create a tag cell for an item.
This is the cell with the "[x]" or "(x)" selector. It also stores the item pointer so the item can later be referenced by this tag.
Derived classes are required to implement this.
Implemented in NCItemSelector, and NCCustomStatusItemSelector.
|
virtual |
Return the current item, i.e.
the item that currently has the keyboard focus. Not to be confused with the selected item.
Definition at line 168 of file NCItemSelector.cc.
|
inline |
Return number of the current line, i.e.
the line that has the keyboard focus.
Definition at line 126 of file NCItemSelector.h.
|
protectedpure virtual |
Cycle the status of the current item through its possible values.
For a plain ItemSelector, this means true -> false -> true.
Derived classes are required to implement this.
Implemented in NCItemSelector, and NCCustomStatusItemSelector.
|
virtual |
Delete all items.
Reimplemented from YSelectionWidget.
Definition at line 297 of file NCItemSelector.cc.
|
protected |
Return the desription text for an item.
The result may contain newlines.
Definition at line 266 of file NCItemSelector.cc.
|
inline |
Return the text line with the specified line number.
Notice that this is different from the item index (see getNumLines()).
Definition at line 155 of file NCItemSelector.h.
|
inline |
Return the number of lines in this widget.
This is different from the number of items because each item always has one line for the item label, optionally multiple lines for the description, and optionally a separator line between it and the next item.
Definition at line 120 of file NCItemSelector.h.
|
virtual |
Return the preferred height for this widget.
Reimplemented from YWidget.
Definition at line 98 of file NCItemSelector.cc.
|
virtual |
Return the preferred width for this widget.
Reimplemented from YWidget.
Definition at line 92 of file NCItemSelector.cc.
|
protected |
If the cursor is not on the first line of an item (the line with the "[x]" selector), scroll up to the next line that is the first line of an item.

Notification that a status value was just changed in the input handler and the 'notify' flag is set.
The returned event is used as the return value of the input handler (unless it has event type 'none' which is also returned by the default constructor of NCursesEvent), i.e. it is sent to the application.
Derived classes are required to implement this.
Implemented in NCItemSelector, and NCCustomStatusItemSelector.
