hello frenz... i want to make a swing GUI that looks like general editors like Eclipse where we have certain frames and any frame can be maximised closed etc... I have made that but the problem is I want that suppose I have three JInternalFrames viz left, center and bottom like left will contain a JTree, Center will contain my other GUI and bottom will contain other frames... now what I want is when i close a particular frame other two JinternalFrames should occupy its space and when its again invokedit should get back its position and the other two should move to their original size...
You can have a look at eclipse to get a view of what i want to make... is it made in Java Swings or something else... please help

thanx in advance

hi frenz.. i m making an application in which I m calling servlets from Swing applications. these servlets are talking to database and performing some operations. so far fine.
these opeartions are time consuming.. so I thought of using SwingUtilities. invokelater(). but I want to get return values from these operations which will be taking place in runnable objects run method. compiler is saying these values should be final. but i want to use these values in other parts of the programs.
i.e. after servlet is done with its work.. it returns a value... I want to work with that value...plz help if anybody have any idea. plz make sure reply is easy to understand coz i m not perfect.

hello frenz... I dont know if this question is to be asked in this group or not if not then plz forgive.. Actually i hv made and application in which I m supposed to start some device and then store the Start date and timein MySQL and then retrieve that date and time and show in GUI...
in java side I m using java.util.Date and in MYSQL table I m using simple Date(I guess that is java.sql.Date)

Now problem is I m getting the Date from GUI and converting it into java.sql.Date and then inserting. but it is storing only 0000-00-00. I dont know whats going wrong. i tried forums but none is clear enough. plz help me out

I want to show time also. I dont want to change either so plz give any round about.

code to enter java date in mysql is:


java.util.Date startTime = obj.getOperationTime();
java.sql.Date time=new java.sql.Date(startTime.getTime());

String updatdev = "update DeviceApplication set DeviceApplicationStatus ="
+ status + ", DeviceApplicationStartTime =" + new java.sql.Date(startTime.getTime())+ " where DeviceApplicationID =" + deviceID;
//Execute the Query
int i = stmt.executeUpdate(updatdev);



plz help

hi frenz... i have a problem regarding JTree and JToolBar...
what i m doing is..

when my application starts i m making a GUI which contains a panel which shows
1) JTree
2) JMenu
3) JToolBar.

JTree is constructed from nodes which is constructed from fields from database.. thus the nodes(objects) are created when applications starts.
(by connecting to database).

In the JToolBar and JMenuBar, I m using actions to which I m sending this JTree as parameter. these actions are using this JTree to perform Operations. these operations include adding Nodes to JTree. I m able to do that..i.e. adding nodes to JTree model and Database and the node is successfully added in JTree view but the problem is after adding or deleting the nodes when I check for the parents , they contain same elements as when the application started..


when I restart the application all the data is again fetched from database and JTree is constructed. The problem is obvious that i passed the JTree, which i constructed when the application started, as argument and it is still working on that parameter.. what i want is that whenever any change occurs in JTree i.e adding or deleting , changes should be applicable from that very moment.. I m troubled by this.. plz help with detailed and clear example.
thanx in advance

hi frenz ... my problem is I m making an application in which there are many JInternalFrames. I want to maximise or minimise them from Menu. code I m using is

if(!(frame.isMaximizable())){
frame.getDesktopPane().getDesktopManager().minimizeFrame(frame);
frame.setMaximizable(true);
JInternalFrame[] frames=desktop.getAllFrames();
for(int i=0;i<frames.length;i++)
frames[i].setLayer(i);
frame.setLayer(32767);
}
else{

frame.getDesktopPane().getDesktopManager().maximizeFrame(frame);
frame.setMaximizable(false);

}




but problem is that neither window does not maximise properly. it comes over another window.partially maximised partially below other frames. what could be the problem. plz answer. thanx in advance
