Tabstrip

Definition

A container that enables the user to switch between several panels -by clicking on the tab - that appear to share the same space on the screen. The user can view a particular panel by clicking its tab. Use tabStripItem to define the panel size and title. Use tabStripItemBody to define the layout of the tabStripItem. Use tabStripItemHeader to change the settings of the title (specified through tabStripItem).

bodyHeight

Defines the height of panel. The tabs are added on top of panel. The height of the tabs is defined by used text font.
horizontalAlignment

Defines the horizontal alignment of the tapStripItems.
- LEFT
  
  Left justifies the content of the cell.
- RIGHT
  
  Right justifies the content of the cell.
- CENTER
  
  Centers the content of the cell.
- CHAR

id

selection

tooltip

Defines the hint of the tab which is displayed as the mouse cursor passes over the panel of the tabStrip, or as the mouse button is pressed but not released.
verticalAlignment

Defines the vertical alignment of the tapStripItems.
- BASELINE
  
  The content of the cell is aligned on the baseline line of the cell (or bottom when no baseline exits).
- BOTTOM
  
  The content of the cell is aligned to the bottom line of the cell.

bodyHeight		Unit (100)	Taglib bodyHeight="100" Classlib setBodyHeight("100")
horizontalAlignment		CENTER (d) CHAR JUSTIFY LEFT RIGHT	Taglib horizontalAlignment="LEFT" Classlib setHorizontalAlignment(CellHAlign.LEFT)
id	*	String (cs)	Taglib id="TabbedNotebook" Classlib setId("TabbedNotebook")
selection		Numeric (1)	Taglib selection="3" Classlib setSelection(3)
tooltip		String	Taglib tooltip="select a tab" Classlib setTooltip("select a tab")
verticalAlignment		BASELINE BOTTOM MIDDLE TOP (d)	Taglib verticalAlignment="MIDDLE" Classlib setVerticalAlignment(CellVAlign.MIDDLE)
width		Unit (400)	Taglib width="200" Classlib setWidth("200")

tabStripItem

Specifies the panel size and the tab of a tabStrip. Use tabStripItemBody to define the layout of the tabStripItem. Use tabStripItemHeader to change the settings of the title later on. A tabStripItem must have a unique 'id' and 'index' attribute and can call a specific event handler that is activated when this tab is clicked.

header

The tab can have text (set by the 'title' attribute) or any other control. 'header' specifies the component. Common use would be to display icons in the tabs (instead of text).
height

Defines the height of the tabStripItem.
id

Identification name of the tabStripItem.
index

Defines the index of the tabStripItem. The 'selection' attribute of the tabStrip refers to the 'index'. The 'index' is mandatory and can be alphanumeric.
onSelect

Defines the event handling method that will be processed when the user clicks on the tab. The string for the event name is not case sensitive - the reference however has to be spelled exactly the same way as the definition of the 'onSelect' event.

If you define a 'onSelect' event, you have to switch to the new selected tab in your application, using the tabstrip method selection (see above). If you do not define a 'onSelect' event the tab can be clicked, the selected tab is displayed, but no event is generated.
title

Defines the text that is displayed in the tab itself.
tooltip

Defines the hint of the tab which is displayed as the mouse cursor passes over the panel of the tabStrip, or as the mouse button is pressed but not released.
width

Defines the overall width of the tabStripItem.

Attributes	M	Values	Usage
header		Component	Taglib No tag available Classlib setHeader(htmlb.Image("icon.gif", "Text title")
