how can i add more than 500 jPanels in a jScrollPane
Hello to all ,
I am facing a problem related to adding jPanels in jScrollPane. My application needs more than 500 jpanels in the jscrollpane.where in each jPanel 4 jtextboxes, 1 comboboxes, 1 check box is there.when the check box will be clicked then the total row( ie row means the panel containing the 4 jtextboxes, 1 comboboxes, 1 check box ).and when the user will click on move up or move down button then the selected jpanel will move up or down.
The tool(sun java studio enterprise 8.1) is not allowing more Jpanels to add manually. so i have to add the jpanels by writing the code in to a loop. and the problem is thatwhen i am trying to add the code in the code generated by the tool the code written out side the code by me is not integratable into the tool generated code.
If u watch the code here am sending u ll get what am facing the problem. The idea of creating jpanels through loop is ok but when trying to impleent in tool facing difficulties.
A example code am sending here. please tell me how i can add more panels to the scrollpane(it is the tool generated code)
Thanks in advance , plz help me for the above

> The tool(sun java studio enterprise 8.1) is not allowing more Jpanels to add manually.
This is a Swing forum, not a tool forum. If you don't know how to us the tool then write the code manually and we might be able to help you.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.

Thanks for here kind attention to solve my problem.
I am thinking to create the classes separately for the components (i.e the jpanel, combobox,textbox etc)and call their instaces from the for loop .But the problem is the jpanel will contain the other components and that jpanels (unlimited jpanels will be added later)added to the jscrollpane.
By writing code, the problem is to place components( the comboboxes,textboxes etc placed on the jpanel ) in appropriate coordinates . So i am doing it through tool .
I am sending here the sample code related to my actual need . In this i have taken a jScrollPane, on that i have added jPanel1 and on jPanel1 i have added jPanel2.On jPanel2jTextField1, jComboBox1,jCheckBox are added. If the u ll see the code u can understand what problem i am facing.
If i am still not clearly explained ,please ask me. I need ur help

hi
i guess you need internalframe.. not jScrollPane
http://java.sun.com/docs/books/tutorial/uiswing/components/internalframe.html
regards
Aniruddha

Thanks Aniruddha for your cooperation.
As you mentioned to use jinternalframe ,but according to my application requirement(as my application has jtabbedpan and on each tabs many forms are there ) it will be difficult to use internalframes.
So please sujjest me any other idea about this.If u will read my doubts in previous messages u will get the problem what i am trying to mention.
Regards
Mahendra

have you seen the link i provided you?

Hai Aniruddha
I have seen the link you provided. Information according to my requirement is not there. My requirement is to add Jpanels(containing many textboxes and comboboxes etc) to a jscrollpane through creating a loop and inside the loop i have to call the instances of the respective components . if u just see the code i have given u ll understand my problem.
please sujjest any idea .
Thanks & Regards
Mahendra
# 7
your code is not compilable under standard jdk installation.
add Jpanels(containing many textboxes and comboboxes etc) in JInternalFrame
and in place of the JScrollpane use JDesktopPane
hope that helps you.

Hi Aniruddha,
I have sent the code to your id.Please check that .If u have time please look into this or else its fine .

hi
do not use those GUI builder. they may be good, but not easily customisable. another thing you need to study SWING a lot. if you are working some where then spend some money and take lesson, this time i am sending you a code, but this should not be the way for ever.
this is just basix lession.

{

{

}
}
});
}

frmRet.setBounds(COUNTER * 100, 0, 250, 100);
frmRet.add(getComponentPanel());

return frmRet;
}
private JScrollPane getComponentPanel()

JPanel l_pnl_01 = new JPanel(new GridLayout(1, 3));
l_pnl_01.add(new JTextField("JTextField"));
l_pnl_01.add(new JComboBox());
l_pnl_01.add(new JCheckBox("JCheckBox"));

frm.setVisible(true);
}
}
Best of luck

Thanks for ur patience and help.
That code which you have mentioned i have checked , but that i can not use because my application requirementis different as i have to add many logic to that jpanels and contents inside the panel(like drag n drop, move the panels up or down by clicking to move up/down button, sorting panels according to some conditions etc). and already i am in the mid of the project so i can not build that from the scratch. I hope you can understand what the problem is. If you have any other idea or any specific url where i can get information please refer me.
Regards
Mahendra
