Appendix B. Extended widgets resources and callbacks

This appendix provides a detailed listing of the resources and callbacks for each class in the Extended Widgets subsystem. Note that only the set resource methods are shown in each table, unless a resource only has a get method. Get methods have the same name without the colon. Create/Set/Get (CSG) access designation and default value are listed for each resource and callback.

Callback list set methods are shown, even though callbacks are usually added using addCallback:receiver:selector:clientData:, and not using a callback list set method. These methods end in "Callback:".

The example Table 1. CwArrowButton resource and callback methods in Appendix A, "Widget resources and callbacks" shows how to use the tables in this appendix.

topOrLeftScaleValue:	CSG	0	Specifies the value associated with the slider's current position along the top or left scale, between the minimum and maximum. If the value is out of range, the current value is set to the current maximum or minimum, whichever is closer. This is equivalent to sending setCurrentValue:notify: with the notify parameter set to true.
valueChangedCallback:	C	OrderedCollection new	Specifies the list of callbacks that is called when the value of the slider has changed. This is called as the result of a button press, arrow key press, or releasing the slider arm after a drag. The reason is XmCRVALUECHANGED. Calldata type is EwSliderValuesCallbackData.

width:	CSG	32	Specifies the width of the column in pixels. This does not includes the width of any emphasis or vertical separator.
EwTableColumn also inherits resource and callback methods from EwTableColumn and Object.

 

Table 110. EwTableList resource and callback methods

cellBlockSelection- Callback:	C	OrderedCollection new	Specifies the list of callbacks that is called whenever a block of cells is selected in block selection mode. The reason is XmCRCELLBLOCKSELECT. Calldata type is EwTableListSelectionCallbackData.

headingSeparator- Thickness:	CSG	1	Specifies the thickness of the horizontal line separating the column headings form the rest of the table.
items:	CSG	OrderedCollection new	A collection that represents the items in the list.
itemWidth	G	1	Specifies the width in pixels of items in the list. The value of this resource will be set to the sum of the widths of the columns plus some number of pixels per column for emphasis and separator. This resource is used to set the scrolling interval for the horizontal scroll bar. It is ignored if the scrollHorizontal resource is false.
lockedColumns:	CSG	0	Specifies the number of columns to be locked on the left side of the table. For instance, a value of 2 means that the first 2 columns in the table is locked. A column can be locked only if its preceding column is also locked. When scrolling, the locked columns remain fixed on the left side and all other columns scroll under the locked columns. This value must be no greater than the total number of columns.
rowSeparators:	CSG	false	Specifies whether the rows are separated by a horizontal line.
selectableColumns:	CSG	false	Specifies whether users might select columns by clicking on their headings.
selectedCell	G	nil	Represents a Point whose x component is the index of the column of the selected cell and whose y component is the index of the item (row) of the selected cell. If nil, then no cell is selected. Note: This resource is only relevant if the selection policy is XmCELLSINGLESELECT.
selectedCells	G	nil	Represents a Collection of Points, each of whose x component is the index of the column of the selected cell and whose y component is the index of the item (row) of the selected cell. If empty, then no cell is selected. Note: This resource is only relevant if the selection policy is XmCELLSINGLESELECT or XmCELLEXTENDEDSELECT.
selectedColumns:	CSG	#()	An Array of EwTableColumn that specifies the currently selected columns. The columns given must all be members of the columns resource.
selectionPolicy:	CSG	XmBROWSESELECT	Defines the interpretation of the selection action. Allowed values are as follows: XmSINGLESELECT Allows only single selections. XmMULTIPLESELECT Allows multiple selections. XmEXTENDEDSELECT Allows extended selections. XmBROWSESELECT Allows drag and browse functionality XmREADONLYSELECT Allows navigation, but no selection or callbacks. XmCELLSINGLESELECT Allows single selection of cells. If the widget and the column are editable, then selecting a cell causes it to be edited.
separatorsToExtremes:	CSG	false	Specifies whether row and column separators are to be extended to the extreme right and bottom edges of the table.
visualStyle:	CSG	XmFLAT	Defines how cells are displayed. Allowed values are as follows: XmFLAT Looks like a list box. XmETCHROWS Each row is etched. XmETCHCELLS Each cell in an etched column is individually etched. Note: Setting the visual style after the widget is displayed causes the background color to be set to the OS defaults for the visual style given. This means that to override this default, you might need to set the background color again.
