public class Listhead
extends HeadersElement

A list headers used to define multi-columns and/or headers.

Difference from XUL:

1. There is no listcols in ZUL because it is merged into Listhead. Reason: easier to write Listbox.

Default getZclass(): z-listhead.(since 5.0.0)

Listhead

public Listhead()

Method Detail

getListbox

public Listbox getListbox()

Returns the list box that it belongs to.

It is the same as AbstractComponent.getParent().

setColumnshide

public void setColumnshide(boolean columnshide)

Sets whether to enable hiding of listheader with the header context menu.

Note that it is only applied when getMenupopup() is auto.

Since:

6.5.0

isColumnshide

public boolean isColumnshide()

Returns whether to enable hiding of listheader with the header context menu.

Default: true.

Since:

6.5.0

setColumnsgroup

public void setColumnsgroup(boolean columnsgroup)

Sets whether to enable grouping of listheader with the header context menu.

Note that it is only applied when getMenupopup() is auto.

Since:

6.5.0

isColumnsgroup

public boolean isColumnsgroup()

Returns whether to enable grouping of listheader with the header context menu.

Default: true.

Since:

6.5.0

getMenupopup

public String getMenupopup()

Returns the ID of the Menupopup (Menupopup) that should appear when the user clicks on the element.

Default: none (a default menupoppup).

Since:

6.5.0

setMenupopup

public void setMenupopup(String mpop)

Sets the ID of the menupopup (Menupopup) that should appear when the user clicks on the element of each column.

An onOpen event is sent to the popup menu if it is going to appear. Therefore, developers can manipulate it dynamically (perhaps based on OpenEvent.getReference) by listening to the onOpen event.

Note: To simplify the use, it ignores the ID space when locating the component at the client. In other words, it searches for the first component with the specified ID, no matter it is in the same ID space or not.

If there are two components with the same ID (of course, in different ID spaces), you can specify the UUID with the following format:
uuid(comp_uuid)

Parameters:

mpop - an ID of the menupopup component, "none", or "auto". "none" is assumed by default, "auto" means the menupopup component is created automatically.

Since:

6.5.0
