printPanel()

Prints a panel.

Synopsis

int printPanel(string modulName, string panelName, string spec, int options);

Parameters

Parameters	Description
modulName	Module in which the panel to be printed is located
panelName	panel to be printed
spec	Default = "" and means print with child panels (is printed like a screenshot), "panelOnly" = prints the panel without child panels (without screenshot of the child panels).
options	With the options parameter the available printing options can be defined. Following constants (values) are available: PPO_NO_DIALOGS (0) - opens no dialogs PPO_ALL_DIALOGS (1) - opens all dialogs [default] PPO_PRINTER_DIALOG (2) - only the print dialog will be opened PPO_BACKGROUND_DIALOG (4) - only the background options dialog will be opened The background options dialog is used to define wether the background color should be replaced with white or should not be changed.

Return value

The function printPanel() returns 0 or in the event of errors, -1.

Description

The function printPanel() prints out a panel panelName in a module modulName.

Printing

When you want to print a panel, a printer settings window opens. The printer settings window opens by default. The options parameter you can define wether all windows are opened or only the printer window/background color window.

The examples below show how to print a panel by either using the attributes of the internal data point or by using the parameter to open the printer settings window.

The associated data point elements of the internal _Ui data point are:

Data point element at the DP node _Ui_X.Print ("X" stands for the number of the UI)	Data type	Description
.PrinterName	string	Printer name or file name. In silent mode or without print dialog, the printout can be also redirected to a local file. The supported formats are PDF (.pdf) and Postscript (.ps). Syntax: "file:///path/file.pdf"; Examples: Linux: "file:///tmp/file.pdf"; Windows: "file:///C:/Temp/file.ps";
.Landscape	bool	Landscape or Portrait
.Background	bool	off = the background color of the panel will be printed in white.
.Scale	float	Scaling factor
.FitToPage	bool	Allows scaling irrespective of the printer default.

EXAMPLE

In the following example, the available printers are first queried with the function getPrinterNames(). A panel will be printed on an available printer. The printer settings are selected through the internal UI data point.

Instead of a dpSet() a dpSetWait() should be used, as otherwise the UI may not get the new hotlink in case of a new printPanel() call and the old/previous values are taken over from the DP.

main()

{

dyn_string name, share;

getPrinterNames(name, share);

/* Function to query the names of the available printers */

DebugN(name);

DebugN(share); /*use a printer that is saved in this variable */

int PDruck;

/* Set the printer settings. The settings of the UI data point with the number 4, are set. The panel is printed on the third available printer. The landscape format is not used, the background is white and scaling is not used */

dpSetWait("_Ui_4.Print.PrinterName:_original.._value", share[3], "_Ui_4.Print.Landscape", FALSE, "_Ui_4.Print.Background", FALSE, "_Ui_4.Print.Scale", 0, "_Ui_4.Print.FitToPage", FALSE);

string modulName = myModuleName(); /* the current module is used*/

string panelName = "print_panel"; /* A panel called "print_panel" is printed */

int options = PPO_NO_DIALOGS; //No dialog is used

PDruck = printPanel(modulName,panelName,"panelOnly", options); /* The panel "print_panel" in the current module, is printed, the print settings window is not shown */

DebugN("Function successful if value=0",PDruck );

}

The following example shows how to print a panel using the printer settings window. A panel called "print_panel" will be printed in the current module.

main()
{

int panelDr;

string panelName = "print_panel";

string modulName = myModuleName();

int options = PPO_PRINTER_DIALOG; //opens the printer settings window

panelDr = printPanel (modulName,panelName,"panelOnly", ShowDialog);

DebugN("Function successful ", panelDr, modulName, panelName,options);

}

Example

The following example prints the current panel in the current module on the default printer without special options.

main()
{

printPanel(myModuleName(), myPanelName());

}

Example

Prints a panel from the panel topology (with naviModule, mainModule and infoModule).

#uses "pt.ctl"

main()

{

int ModuleNumber;

string modName;

string curr_mode = myModuleName();

pt_moduleNumber(curr_mode,ModuleNumber);

modName = pt_buildModuleName("mainModule", ModuleNumber);

string panelName = rootPanel(pt_buildModuleName("mainModule", ModuleNumber));

printPanel(modName,panelName);

}
