f$Structure_open (f$Struktur_oeffnen)

A structure dialog is opened with this function. As many structure dialogs as desired can be opened simultaneously. For ease of use, you should aim to keep only one structure dialog visible in the set of rules by switching inactive structure dialogs to invisible. The structure dialogs can be opened in two modes. Links can be inserted during maintenance by right-clicking on two nodes. Furthermore, you can move and delete nodes in this mode.

Syntax:	Structure number = f$Struktur_oeffnen( usage , Name, Title, X , Y , Width , Height,[PGName] )
	Argument	Type	Meaning
	Usage	Integer	0 – Open the structure dialog for runtime 1 – Open the structure dialog for maintenance
	Name	String	Name of the structure dialog.
	Title	String	Text in the structure dialog This text is displayed in the title line.
	X	Integer	Upper-left corner of the structure dialog in pixels
	Y	Integer	Upper-left corner of the structure dialog in pixels
	Width	Integer	Width of the structure dialog in pixels
	Height	Integer	Height of the structure dialog in pixels
	PGName	String	This parameter is optional If it is entered, it presents the name of a parameter group giving additional information to the structure dialog Currently evaluated parameter in the parameter group: XRaster – x-axis dimensions for the grid on which nodes are captured. YRaster – y-axis dimensions for the grid on which nodes are captured. XRasterPos – left edge of the grid. YRasterPos – top edge of the grid.
Result:	Integer	Number for use with other functions, or –1 if an error has occurred.
Example:	StructureNumber = f$Structure_open(1, Form, 'Form: ' + Form,10, 100, 800, 600)
