Class Style

java.lang.Object
  org.zkoss.zk.ui.AbstractComponent
      org.zkoss.zul.Style

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Component, Scope, ComponentCtrl

public class Style
extends AbstractComponent

The style component used to specify CSS styles for the owner desktop.

Note: a style component can appear anywhere in a ZUML page, but it affects all components in the same desktop.

There are two formats when used in a ZUML page:

Method 1: Specify the URL of the CSS file

<style src="my.css"/>
 

Method 2: Specify the CSS directly

<style>
 .mycls {
  border: 1px outset #777;
 }
</style>
 

Note: if the src and content properties are both set, the later one overrides the previous one.

public java.lang.String getSrc()

Returns the URI of an external style sheet.

Default: null.

setSrc

public void setSrc(java.lang.String src)

Sets the URI of an external style sheet.

Parameters:

src - the URI of an external style sheet

See Also:

setContent(java.lang.String)

getMedia

public java.lang.String getMedia()

Returns the media dependencies for this style sheet.

Default: null.

getContent

public java.lang.String getContent()

Returns the content of the style element. By content we mean the CSS rules that will be sent to the client.

Default: null.

Deriving class can override this method to return whatever it prefers (ignored if null).

Since:

3.0.0

setContent

public void setContent(java.lang.String content)

Sets the content of the style element. By content we mean the CSS rules that will be sent to the client.

Calling this method implies setSrc(null). In other words, the last invocation of setContent(java.lang.String) overrides the previous setSrc(java.lang.String), if any.

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException

Description copied from class: AbstractComponent

Called by (ComponentCtrl.redraw(java.io.Writer)) to render the properties, excluding the enclosing tag and children.

Default: it renders AbstractComponent.getId() if it was assigned, and event names if listened (and listed in AbstractComponent.getClientEvents()).

Note: it doesn't render AbstractComponent.getWidgetClass(), AbstractComponent.getUuid() and AbstractComponent.getMold(), which are caller's job.

Overrides:

renderProperties in class AbstractComponent

Throws:

java.io.IOException

Not allowed.

Specified by:
