- access: public

boolean getCausesValidation ()
getCoordinates (line 343)

- return: coordinates defining the hotspot shape.
- access: public
- abstract:

string getCoordinates ()

Redefined in descendants as:

- TCircleHotSpot::getCoordinates()
- TRectangleHotSpot::getCoordinates()
- TPolygonHotSpot::getCoordinates()

getHasAttributes (line 494)

- return: whether the hotspot has custom attributes
- access: public

boolean getHasAttributes ()

- TCircleHotSpot::getShape()
- TRectangleHotSpot::getShape()
- TPolygonHotSpot::getShape()

getTabIndex (line 428)

- return: the tab index of the HotSpot region. Defaults to 0.
- access: public

integer getTabIndex ()
getTarget (line 477)

- return: the target window or frame to display the new page when the HotSpot region is clicked. Defaults to ''.
- access: public

string getTarget ()
getValidationGroup (line 460)

- return: the group of validators which the hotspot causes validation upon postback
- access: public

- return: the viewstate value corresponding to $key
- access: protected

mixed getViewState (string $key, [mixed $defaultValue = null])

- string $key: the name of the viewstate value to be returned
- mixed $defaultValue: the default value. If $key is not found in viewstate, $defaultValue will be returned

hasAttribute (line 523)

- access: public

boolean hasAttribute (mixed $name)
removeAttribute (line 557)

Removes the named attribute.

- return: attribute value removed, null if attribute does not exist.
- access: public

string removeAttribute (string $name)

- string $name: the name of the attribute to be removed.

render (line 569)

Renders this hotspot.

- access: public

void render (THtmlWriter $writer)

- THtmlWriter $writer

setAccessKey (line 356)

- access: public

void setAccessKey (string $value)

- string $value: the access key that allows you to quickly navigate to the HotSpot region.

setAlternateText (line 372)

- access: public

void setAlternateText (string $value)

- string $value: the alternate text to display for a HotSpot object.

setAttribute (line 547)

Sets a custom hotspot attribute.

- string $value: value of the attribute

setCausesValidation (line 452)

- access: public

void setCausesValidation (boolean $value)

- boolean $value: whether postback event trigger by this hotspot will cause input validation

setHotSpotMode (line 388)

- access: public

void setHotSpotMode (THotSpotMode $value)

- THotSpotMode $value: the behavior of a HotSpot object when it is clicked.

setNavigateUrl (line 404)

- access: public

void setNavigateUrl (string $value)

- string $value: the URL to navigate to when a HotSpot object is clicked.

setPostBackValue (line 420)

- access: public

void setPostBackValue (string $value)

- string $value: a value that is post back when the HotSpot is clicked.

setTabIndex (line 436)

- access: public

void setTabIndex (integer $value)

- integer $value: the tab index of the HotSpot region.

setTarget (line 486)

- access: public

void setTarget (string $value)

- string $value: the target window or frame to display the new page when the HotSpot region is clicked.

setValidationGroup (line 468)

- access: public

void setValidationGroup (string $value)

- string $value: the group of validators which the hotspot causes validation upon postback

setViewState (line 328)
