Hi,
I am looking for at way to print HTML pages from an SWT application,
preferably using the SWT Browser widget. Is there a way to get the
browser widget to print the current contents? Or any suggestions for
good alternatives?
Thanks,
Thomas P. Boesen

This is my solution for Windows SWT:
package org.eclipse.swt.browser;
import org.eclipse.swt.browser.Browser;
import org.eclipse.swt.ole.win32.*;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Composite;
public class PrintableBrowser extends Browser {
public PrintableBrowser(Composite parent, int style) {
super(parent, style);
}
public void print(boolean showStdSetupDialog) {
checkWidget();
int[] rgdispid = auto.getIDsOfNames(new String[]
{ "ExecWB",
"cmdID","cmdexecopt" });
Variant[] rgvarg = new Variant[2];
//OLECMDID_PRINT is const from MS headers
rgvarg[0] = new Variant(OLE.OLECMDID_PRINT);
//OLECMDEXECOPT_PROMPTUSER = 1
//OLECMDEXECOPT_DONTPROMPTUSER = 2
rgvarg[1] = new Variant(showStdSetupDialog ? 1 :
2);
int[] rgdispidNamedArgs = new int[2];
rgdispidNamedArgs[0] = rgdispid[1];
rgdispidNamedArgs[1] = rgdispid[2];
Variant pVarResult =
auto.invoke(rgdispid[0], rgvarg,
rgdispidNamedArgs);
// If prev code is worked then add error handling
// if(pVarResult.getType() == OLE.VT_EMPTY) {
// throw new
BrowserPrintException(pVarResult.getType());
// }
}
public void pageSetup() {
checkWidget();
int[] rgdispid = auto.getIDsOfNames(new String[]
{ "ExecWB",
"cmdID","cmdexecopt" });
Variant[] rgvarg = new Variant[2];
//OLECMDID_PRINT is const from MS headers
rgvarg[0] = new Variant(OLE.OLECMDID_PAGESETUP);
//OLECMDEXECOPT_PROMPTUSER = 1
//OLECMDEXECOPT_DONTPROMPTUSER = 2
rgvarg[1] = new Variant(1);
int[] rgdispidNamedArgs = new int[2];
rgdispidNamedArgs[0] = rgdispid[1];
rgdispidNamedArgs[1] = rgdispid[2];
Variant pVarResult =
auto.invoke(rgdispid[0], rgvarg,
rgdispidNamedArgs);
// If prev code is worked then add error handling
// if(pVarResult.getType() == OLE.VT_EMPTY) {
// throw new
BrowserPrintException(pVarResult.getType());
// }
}
}
