Use of Images on Buttons.

Images can be specified as local to the device or on an HTTP / FTP server, just specify the required protocol as part of your URL (file://\, HTTP:// and FTP://). Image will be scaled to the size of the button. JPEG and GIF images are only supported on WM devices. Both CE and WM support BMP files.

Default Positions

By default this control will be placed a the top of the screen. On Windows Mobile if the 'FullScreen' configuration setting is disabled the control will need to be moved, otherwise it will appear beneath the task bar.

Switching to Other Applications

All controls are designed to be shown on top of PocketBrowser. If you require to switch to an application other than PocketBrowser you should minimize PB to ensure the buttons do not remain shown.

Visibility of Stop Button

Depending on how quickly the navigation is completed, whether the target page is cached, and what operating system the device is using, the stop button may not be visible immediately after starting navigation.

Screen Orientation

When the screen orientation changes, either using the ScreenOrientation tag or by rotating a device with hardware support, the command areas will automatically move and resize to fit the new layout. However the buttons themselves are not moved and in some cases this may result in them being off the screen or not in the expected position. If so they must be moved manually by detecting the ScreenOrientationEvent.
