public class ModalWindow

extends wicket.markup.html.panel.Panel

Modal window component.

Modal window is a draggable window (with either div or iframe content) that prevent user from interacting the rest of page (using a mask) until the window is closed.

The window is draggable and optionally resizable. The content can be either

• a component - you need to add the component to modal window (with id obtained using getContentId(), or
• a page - you need to pass a ModalWindow.PageCreator instance to a setPageCreator(ModalWindow.PageCreator) method.

In case the content is a component, it is not rendered until the window is shown (method show(AjaxRequestTarget)). In case the content is another page, you can set the desired pagemap name using setPageMapName(String). Setting pagemap is only needed when wicket multiwindow support is on.

The window can be made visible from an ajax handler using show(AjaxRequestTarget).

To close the window there are multiple options. Static method close(AjaxRequestTarget) can be used to close the window from a handler of ajax link inside the window. By default the close button in the upper right corner of the window closes it. This behavior can be altered using setCloseButtonCallback(ModalWindow.CloseButtonCallback). If you want to be notified when the window is closed (either using the close button or calling close(AjaxRequestTarget)), you can use setWindowClosedCallback(ModalWindow.WindowClosedCallback).

Title is specified using setTitle(String). If the content is a page (iframe), the title can remain unset, in that case title from the page inside window will be shown.

There are several options to specify the visual properties of the window. In all methods where size is expected, width refers to width of entire window (including frame), height refers to the height of window content (without frame).

• setResizable(boolean) specifies, whether the window can be resized.
• setInitialWidth(int) and setInitialHeight(int) specify the initial width and height of window. If the window is resizable, the unit of these dimensions is always "px". If the window is not resizable, the unit can be specified using setWidthUnit(String) and setHeightUnit(String). If the window is not resizable and the content is a component (not a page), the initial height value can be ignored and the actual height can be determined from the height of the content. To enable this behavior use setUseInitialHeight(boolean).
• The window position (and size if the window is resizable) can be stored in a cookie, so that it is preserved when window is close. The name of the cookie is specified via setCookieName(String). If the name is null, position is not stored (initial width and height are always used). Default cookie name is null (position is not stored).
• setMinimalWidth(int) and setMinimalHeight(int) set the minimal dimensions of resizable window.
• Modal window can chose between two colors of frame. setCssClassName(String) sets the dialog css class, possible values are CSS_CLASS_BLUE for blue frame and CSS_CLASS_GRAY for gray frame.
• Mask (element that prevents user from interacting the rest of the page) can be either transparent or semitransparent. setMaskType(ModalWindow.MaskType) alters this.
