Re: *****SPAM***** [equinox-dev] Problem with showing popup message in Custom Install Handler

Hardik,

       You could Try this snippet:

Display display = Display.getDefault();
display.syncExec( new Runnable(){
public void run() {
Shell s = new Shell(display);
MessageDialog dialog = new MessageDialog(s, "Message here", display.getSystemImage(SWT.ICON_WARNING), "some text",SWT.ICON_WARNING, new String[] { "OK" }, 0);
dialog.setBlockOnOpen(true);
dialog.open();
}
});


Regards,

Gladyston

Hello All,



I am using Eclipse 3.3 for plug-in development. We have used Custom Install Handler to customize plug-in installation for our requirement. We wrote a InstallHandler with extending BaseInstallHandler class and override completeInstall() and completeUninstall() methods. But we want to display popup message to user during feature un-installation.



I have tried with MessageDialog.openInformation() in completeUninstall() method but it throws NullPointerException while executing getSystemImage() method of SWT class.

I have also tried with ErrorDialong.openError()in completeUninstall() method but it throws SWTException:Invalid Thread Access

When tried with PopupDialog it requires parent shell that is not there in InstallHandler code.



Please provide your valuable suggestion for implementation strategy.



Thanks & Regards,

-Hardik
