This is a global built-in package that provides interfaces for manipulating top level user interface objects, such as top level windows and panels. Hot key bar event processing also happens through this interface.

Opening windows explicitly using the functions in this interface should be done carefully, in order to preserve the integrity of the program data base on client instances. Generally, windows should only be opened once shared from the host, or by using requestNewClientWindow to notify the host of the new window and its data.

function openWindow(windowclass, datasource)

Creates a top level window by a windowclass and a datasource. If a matching window already exists, it is returned. Otherwise, a new window is created.

See windowinstance for more information on the parameter values.

Parameters

windowclass   (string)   

The windowclass of the window to create

datasource   (string)   

The name of the datasource to use, see windowinstance for details

Return values

(windowinstance)
A windowinstance to the window, or nil if the request failed.

requestNewClientWindow

function requestNewClientWindow(windowclass, rootnode)

Because client instances should not create windows with data bound to nonexistant database nodes, they need to ask the host to create a new data base node to act as the window datasource whenever a new record is required. This function sends a request to do this to the host asynchronously, with the host responding with an acknowledgement to create a new window instance if successful.

Due to the asynchronous nature of this function, it does not return a reference to the window, returning immediately. If any further processing is required, other means to process the created window are required.

A new datasource node will be created for the window. The host will create a new unique node under the node passed as the second parameter, i.e. the datasource node will be a child of the node specified in the root node parameter.

It is possible to create client windows with openWindow. This option should be reserved for special cases and should not be used under normal circumstances.

Parameters

windowclass   (string)   

The windowclass of the window to create

rootnode   (string)   

The name of the parent node used to create the data source, see above and windowinstance for details


setLighting

function setLighting(systemcolor, windowcolor, controlcolor, contentcolor)

This function can be used to change the ambient lighting of the user interface elements. The color change will take place on all connected clients gradually over a couple of seconds.

All the color components are specified as strings in the form "BBGGRR", where the characters are hexadecimal digits specifying the red, green and blue color channels in the range 0 .. 255. The colors will be modulated with the pixel values in the bitmaps defining the interface.

All parameters other than windowcolor are ignored.

Warning
The parameter values expect color strings in a different format than all other FG API functions. (BBGGRR)

Parameters

systemcolor   (string)   

The color used to render system interface elements

windowcolor   (string)   

The color used to render window frame interface elements

controlcolor   (string)   

The color used to render control elements

contentcolor   (string)   

The color used to render user specified content interface elements. Please note that changing this value may affect the usability of the respective content.


setString

function setString(id, text)

Sets the text of a string resource.

Parameters

id   (string)   

String resource ID

text   (string)   

Text to store in the string resource


toggleWindow

function toggleWindow(windowclass, datasource)

If a top level window with the specified windowclass and datasource exist, it is brought to the top of the window Z-order. If it was already at the top of the Z-order, it will be closed. If it does not exist, then a new window will be created with the specified windowclass and datasource.

See windowinstance for more information on the parameter values.

Parameters

windowclass   (string)   

The windowclass of the window to toggle

datasource   (string)   

The name of the datasource to use, see windowinstance for details

Return values
