window caption

information text

 

The window caption and information text elements are text variables representing the text displayed on the upper and lower window border. The variables can both be read and entered. The status bar on the window lower border will be displayed only if the information text is not empty. If the status bar is to be displayed without any text, a space character has to be displayed.

delete element/window

 

The delete element/window command serves to delete a dialog element or a dialog window. As a command parameter an element or a window identification number is entered.

 

element identification number

 

The element number element is a numeric variable indicating, which dialog element or dialog window it will be manipulated with (dimension changes etc.). After a dialog window or a dialog element is created, the variable is automatically set to the newly created window/element. As an identification number the number returned by the window/element operation is used. A special case is the number 0, which is the program main window identification number. The properties of the program main window can be adjusted, but the window cannot be deleted. Another special case is the number -1, identifying the Windows desktop. This number serves only to find out the Windows desktop user size (without border bars; elements internal width and internal height), and to find out the display dimensions (elements width and height). No other operations can be carried out with the desktop.

 

graphic background

 

The graphic background element is a logic switch. If it is set, the program graphic surface is displayed instead of the unicolored background of the main window in the dialog mode. Thus the Peter application’s graphics can be combined with dialog elements.
