SAP ABAP NetWeaver Tutorial

In some case, we need to pop up a new window to show some more data. Here, I will introduce how to pop up a new window using web dynpro Java.

Step 1. Create a new window in your WD component.

Step 2. Embeded a view or viewset in the widow.

Step 3. Create a new value node and value attribute.

This value node is used to store the reference to the window instance. The value attribute should be the type of ‘com.sap.tc.webdynpro.services.session.api.IWDWindow‘.

Step 4. Add code to pop up a new window in an action.

Add below code to your action to show your pop up window.

    //show the pop up window
	IWDWindowInfo windowInfo = wdComponentAPI.getComponentInfo().findInWindows("Download");
	IWDWindow myWindow = wdComponentAPI.getWindowManager().createModalWindow(windowInfo);
	wdContext.currentPopUpElement().setDownLoadWindow(myWindow);
	myWindow.setWindowSize(300 , 80);
	myWindow.setWindowPosition(WDWindowPos.CENTER);
	myWindow.show();

In the pop up window, there is a close button to close current pop up window. You should add below code to the close action.

	wdContext.nodePopUp().currentPopUpElement().getDownLoadWindow().destroyInstance();

Now everything is ready. You can use the pop up screen in your own web dynpro applicaiton. Enjoy it:-)
