Method Detail

browserDebugger

@Deprecated
public static void browserDebugger()

Deprecated. As of 7.4.0, use WidgetUtil.browserDebugger() instead.

Helper method for debugging purposes. Stops execution on firefox browsers on a breakpoint.

getKeyCode

@Deprecated
public static int getKeyCode( event)

Deprecated. As of 7.4.0, use WidgetUtil#getKeyCode(KeyEvent) instead.

Helper method for a bug fix #14041. For mozilla getKeyCode return 0 for space bar (because space is considered as char). If return 0 use getCharCode.

Parameters:

event -

Returns:

return key code

Since:

7.2.4

getElementFromPoint

@Deprecated
public static com.google.gwt.user.client.Element getElementFromPoint(int clientX,
                                                                                int clientY)

Deprecated. As of 7.4.0, use WidgetUtil.getElementFromPoint(int, int) instead.

Returns the topmost element of from given coordinates. TODO fix crossplat issues clientX vs pageX. See quircksmode. Not critical for vaadin as we scroll div istead of page.

Parameters:

x -

y -

Returns:

the element at given coordinates

notifyParentOfSizeChange

@Deprecated
public static void notifyParentOfSizeChange(Widget widget,
                                                       boolean lazy)

Deprecated. As of 7.0, use LayoutManager.setNeedsMeasure(ComponentConnector) instead

This helper method can be called if components size have been changed outside rendering phase. It notifies components parent about the size change so it can react. When using this method, developer should consider if size changes could be notified lazily. If lazy flag is true, method will save widget and wait for a moment until it notifies parents in chunks. This may vastly optimize layout in various situation. Example: if component have a lot of images their onload events may fire "layout phase" many times in a short period.

Parameters:

widget -

lazy - run componentSizeUpdated lazyly
