Method Detail

onActivate

void onActivate(Panel panel)

Fires after the Panel has been visually activated. Note that Panels do not directly support being activated, but some Panel subclasses do (like Window). Panels which are child Components of a TabPanel fire the activate and deactivate events under the control of the TabPanel.

Parameters:

panel - this

doBeforeClose

boolean doBeforeClose(Panel panel)

Fires before the Panel is closed. Note that Panels do not directly support being closed, but some Panel subclasses do (like Window). This event only applies to such subclasses. A handler can return false to cancel the close.

Note: that if you want to capture the closing of a tab in a TabPanel, you must listner for the ContainerListener.doBeforeRemove(com.gwtext.client.widgets.Container, com.gwtext.client.widgets.Component) event because closing a tab doesnt close the TabPanel, it just removes it from the parent TabPanel.

Parameters:

panel - this

Returns:

false to cancel

doBeforeCollapse

boolean doBeforeCollapse(Panel panel,
                         boolean animate)

Fires before the Panel is collapsed. A handler can return false to cancel the collapse.

Parameters:

panel - this

animate - true if collapse is animated

Returns:

false to cancel

doBeforeExpand

boolean doBeforeExpand(Panel panel,
                       boolean animate)

Fires before the Panel is expanded. A handler can return false to cancel the expand.

Parameters:

panel - this

animate - true if expand animated

Returns:

false to cancel

onBodyResize

void onBodyResize(Panel panel,
                  java.lang.String width,
                  java.lang.String height)

Fires after the Panel has been resized.

Parameters:

panel - this

width - the new width

height - the new height

onClose

void onClose(Panel panel)

Fires after the Panel is closed. Note that Panels do not directly support being closed, but some Panel subclasses do (like Window).

Note: that if you want to capture the closing of a tab in a TabPanel, you must listner for the ContainerListener.onRemove(com.gwtext.client.widgets.Container, com.gwtext.client.widgets.Component) event because closing a tab doesnt close the TabPanel, it just removes it from the parent TabPanel.

Parameters:

panel - this

onCollapse

void onCollapse(Panel panel)

Fires after the Panel has been collapsed.

Parameters:

panel - this

onDeactivate

void onDeactivate(Panel panel)

Fires after the Panel has been visually deactivated. Note that Panels do not directly support being deactivated, but some Panel subclasses do (like Window). Panels which are child Components of a TabPanel fire the activate and deactivate events under the control of the TabPanel.

Parameters:

panel - this

onExpand

void onExpand(Panel panel)

Fires after the Panel has been expanded.

Parameters:

panel - this

onTitleChange

void onTitleChange(Panel panel,
                   java.lang.String title)
