Class TImageMap

TImageMap class

TImageMap represents an image on a page. Hotspot regions can be defined within the image. Depending on the HotSpotMode, clicking on the hotspots may trigger a postback or navigate to a specified URL. The hotspots defined may be accessed via HotSpots. Each hotspot is described as a THotSpot, which can be a circle, rectangle, polygon, etc. To add hotspot in a template, use the following,

  1. <com:TImageMap>
  2. <com:TCircleHotSpot ... />
  3. <com:TRectangleHotSpot ... />
  4. <com:TPolygonHotSpot ... />
  5. </com:TImageMap>

Method Details

addAttributesToRender

protected void addAttributesToRender (THtmlWriter $writer )

Adds attribute name-value pairs to renderer.

This overrides the parent implementation with additional imagemap specific attributes.

Input
THtmlWriter$writerthe writer used for the rendering purpose
Output
Exception

addParsedObject

public void addParsedObject (string|TComponent $object )

Processes an object that is created during parsing template.

This method adds THotSpot objects into the hotspot collection of the imagemap.

Input
string|TComponent$objecttext string or component parsed and instantiated in template
Output
Exception

getClientClassName

protected string getClientClassName ()

Gets the name of the javascript class responsible for performing postback for this control.

This method overrides the parent implementation.

Output
string the javascript class name
Exception

getHotSpotMode

public THotSpotMode getHotSpotMode ()

Output
THotSpotMode the behavior of hotspot regions in this imagemap when they are clicked. Defaults to THotSpotMode::NotSet.
Exception

getHotSpots

public THotSpotCollection getHotSpots ()

Output
THotSpotCollection collection of hotspots defined in this imagemap.
Exception

getTarget

public string getTarget ()

Output
string the target window or frame to display the new page when a hotspot region is clicked within the imagemap. Defaults to ''.
Exception

onClick

public void onClick (TImageMapEventParameter $param )

Raises OnClick event.

This method is invoked when a hotspot region is clicked within the imagemap. If you override this method, be sure to call the parent implementation so that the event handler can be invoked.

Input
TImageMapEventParameter$paramevent parameter to be passed to the event handlers
Output
Exception

Output
Exception

setHotSpotMode

public void setHotSpotMode (THotSpotMode $value )

Sets the behavior of hotspot regions in this imagemap when they are clicked.

If an individual hotspot has a mode other than 'NotSet', the mode set in this imagemap will be ignored. By default, 'NotSet' is equivalent to 'Navigate'.
