Detailed Description

A table, with rows and columns made out of sub-widgets. Largely inspired by (and can be thought of as a generalisation of) the guichan listbox implementation.

Normally you want this within a ScrollArea.

◆ draw()

void GuiTable::draw ( Graphics *const graphics )

virtual

Draws the widget. It is called by the parent widget when it is time for the widget to draw itself. The graphics object is set up so that all drawing is relative to the widget, i.e coordinate (0,0) is the top left corner of the widget. It is not possible to draw outside of a widget's dimension.

Parameters

graphics aA graphics object to draw with.

Implements Widget.

◆ getChildrenArea()

Rect GuiTable::getChildrenArea ( )

virtual

Gets the area of the widget occupied by the widget's children. By default this method returns an empty rectangle as not all widgets are containers. If you want to make a container this method should return the area where the children resides. This method is used when drawing children of a widget when computing clip rectangles for the children.

An example of a widget that overloads this method is ScrollArea. A ScrollArea has a view of its contant and that view is the children area. The size of a ScrollArea's children area might vary depending on if the scroll bars of the ScrollArea is shown or not.

Returns: The area of the widget occupied by the widget's children.

◆ getWidgetAt()

Widget * GuiTable::getWidgetAt	(	int	x,

virtual

Gets a widget from a certain position in the widget. This function is used to decide which gets mouse input, thus it can be overloaded to change that behaviour.

NOTE: This always returns NULL if the widget is not a container.

Parameters

x	The x coordinate of the widget to get.
y	The y coordinate of the widget to get.

Returns: The widget at the specified coodinate, NULL if no widget is found.

◆ setFocusHandler()

void GuiTable::setFocusHandler ( FocusHandler *const focusHandler )

virtual

Sets the focus handler to be used.

WARNING: This function is used internally and should not be called or overloaded unless you know what you are doing.

Parameters

focusHandler The focus handler to use.

◆ setLinewiseSelection()

void GuiTable::setLinewiseSelection ( bool linewise )

inline

Toggle whether to use linewise selection mode, in which the table selects an entire line at a time, rather than a single cell.

Note that column information is tracked even in linewise selection mode;

this mode therefore only affects visualisation.

Disabled by default.

Parameters

linewise Whether to enable linewise selection mode

113 { mLinewiseMode = linewise; }

References mLinewiseMode.

◆ setModel()

void GuiTable::setModel ( TableModel *const m )

Sets the table model

Note that actions issued by widgets returned from the model will update the table selection, but only AFTER any event handlers installed within the widget have been triggered. To be notified after such an update, add an action listener to the table instead.
