APPENDIX: Desktop Application Framework Parameters

The following meta properties may be used in the head of your web application. For an example that uses most of these tags click on the link at the bottom.

width

Sets the client width of the application (i.e. not including window borders and so forth).

height

Sets the client height of the application.

position

Sets the starting position of the application, in terms of a screen edge. The possible screen edges are top, bottom, left and right. The application will begin in the centre of the specified edge unless a qualifer is present, separated by a hyphen. Possible qualifiers are middle, top, bottom, left and right. This means that top and top-middle are equivalent. However, although top-right and right-top have the same position, they will have different autohide behaviour.

autohide

When used with an anchored edge (see position and anchor) this value indicates that the application should automatically slide off screen when mouse focus is lost. Returning the mouse pointer to that edge of the display slides the application back into view.

chrome

Indicates whether the application should have a border and title bar.

menubar

Indicates whether the application should have a menu bar.

addressbar

Indicates whether the application should have an address bar.

logging

Indicates whether the application should have output and error logging windows.

opacity

Indicates to what extent windows that are behind the application should be visible. The default value of 100 renders the application completely opaque. As values decrease from there, the application becomes more and more faint, allowing obscured windows to become more clearly visible.

transparency

Indicates an RGB hex colour value which is matched against in order to render specific portions of the application completely invisible. Mouse events in these sections will be passed through to whichever window (if any) is behind the application at that point.
