Member Function Documentation

bool t3_widget::smart_label_t::accepts_focus ( void  )
virtual

Query whether this widget accepts focus.

Reimplemented from t3_widget::widget_t.

bool t3_widget::smart_label_t::is_hotkey ( key_t  key)
virtual

Query whether key is a hotkey for this widget.

Reimplemented from t3_widget::widget_t.

bool t3_widget::smart_label_t::process_key ( key_t  key)
virtual

Handle a key press by the user.

Returns
A boolean indicating whether this window_component_t handled the key press.

Implements t3_widget::window_component_t.

void t3_widget::smart_label_t::set_focus ( focus_t  focus)
virtual

Set whether this window_component_t has the input focus.

Note that this merely notifies the window_component_t that it should change it's appearance to indicate the user that this window_component_t has the input focus. Which window_component_t actually receives the input events is handled outside of the window_component_t.

Reimplemented from t3_widget::widget_t.

bool t3_widget::smart_label_t::set_size ( optint  height,
optint  width 
)
virtual

Set the size of this window_component_t.

Parameters
heightThe new height of the window_component_t in cells, or None if it should remain unchanged.
widthThe new width of the window_component_t in cells, or None if it should remain unchanged.
Returns
A boolean indicating whether all allocations required for the resize operation succeeded.

Implements t3_widget::window_component_t.

void t3_widget::smart_label_t::update_contents ( void  )
virtual

Update the contents of the window.

Implements t3_widget::window_component_t.
