Hello,
first of all: i´m a newbie in Netbeans GUI Programming (Swing). I work with Java 6 (1.6.0_04) and Netbeans
6.1.
Yesterday i tried to create a litle MDI-Application and what a surprise - it was really easy. So i delete
the project and created a new one with the same properties. But no i have a problem.
Here what i did:
1)
New -> New Project
2)
Java -> Java Desktop Application
3)
Basic Application
-> The Project is created.
Because i want a MDI-Project i put "Desktop Pane" with Drag&Drop onto the mainPanel (JPanel).
After that i put a "InternalFrame" onto the "Desktop Pane".
Now i want a menu with 2 items. One for closing the InternalFrame and one for opening the InternalFrame.
So i created 2 menuitems and assigned 2 actionEvents->actionPerformed.
In the close-Menu i put the code:
jInternalFrame1.hide();
In the open-menu i put the code:
jInternalFrame1.show();
That was it. So i run the project. And if i click the menuitem to close the form, first of all nothing is
happening. But when i resize the main-form (mainpanel) with the mouse - the internalframe is blanked out.
When i click the menuitem to show the internalframe - everything is working fine.
But in my first project this was working. I can´t remember that i made anything else. What made i wrong?
Where is my mistake?
My project looks like:
Can someone help me please?
Best regards
Heidi
