public Treecell(java.lang.String label,
                java.lang.String src)
Method Detail

getTree

public Tree getTree()
Return the tree that owns this cell.


getTreecol

public Treecol getTreecol()
Returns the tree column associated with this cell, or null if not available.


getColumnIndex

public int getColumnIndex()
Returns the column index of this cell, starting from 0.


getMaxlength

public int getMaxlength()
Returns the maximal length for this cell, which is decided by the corresponding getTreecol()'s Treecol.getMaxlength().


getLevel

public int getLevel()
Returns the level this cell is. The root is level 0.


getSpan

public int getSpan()
Returns number of columns to span this cell. Default: 1.


setSpan

public void setSpan(int span)
Sets the number of columns to span this cell.

It is the same as the colspan attribute of HTML TD tag.


getZclass

public java.lang.String getZclass()
Description copied from class: HtmlBasedComponent
Returns the ZK Cascading Style class(es) for this component. It usually depends on the implementation of the mold (@{link #getMold}).

Default: null (the default value depends on element).

HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

Overrides:
getZclass in class HtmlBasedComponent
See Also:
HtmlBasedComponent.getSclass()

clone

public java.lang.Object clone()
Description copied from interface: Component
Clones the component. All of its children and descendants are cloned. Also, ID are preserved.

Specified by:
clone in interface Component
Overrides:
clone in class LabelImageElement
Returns:
the new component. Notice that it doesn't belong to any page, nor desktop. It doesn't have a parent, either.

getWidth

public java.lang.String getWidth()
Returns the width which the same as getTreecol()'s width.

Overrides:
getWidth in class HtmlBasedComponent

setWidth

public void setWidth(java.lang.String width)
Deprecated. as of release 6.0.0. To control the width of Treecell, please use HtmlBasedComponent.setWidth(String) instead.

Description copied from class: HtmlBasedComponent
Sets the width. If null, the best fit is used.

Overrides:
setWidth in class HtmlBasedComponent
See Also:
HtmlBasedComponent.setWidthDirectly(java.lang.String), AbstractComponent.disableClientUpdate(boolean)

setHflex

public void setHflex(java.lang.String flex)
Deprecated. as of release 6.0.0. To control the hflex of Treecell, please use HtmlBasedComponent.setHflex(String) instead.

Description copied from class: HtmlBasedComponent
Sets horizontal flex hint of this component.

Number flex indicates how this component's container distributes remaining empty space among its children horizontally. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios.

Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1.

Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components.

Overrides:
setHflex in class HtmlBasedComponent
Parameters:
flex - horizontal flex hint of this component.

HtmlBasedComponent.setVflex(java.lang.String), HtmlBasedComponent.getHflex()

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException
Description copied from class: HtmlBasedComponent
Renders the content of this component, excluding the enclosing tags and children.

beforeParentChanged in class AbstractComponent
Parameters:
parent - the new parent. If null, it means detachment.
