Hi,
I am trying to pop up swing calendar in a Jpanel.it works fine when i give
.add(component) inside initComponents()

calendar = new JCalendar();
jPanel2Layout.setHorizontalGroup(
jPanel2Layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
.add(0, 170, Short.MAX_VALUE).add(calendar);
jPanel2Layout.setVerticalGroup(
jPanel2Layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
.add(0, 120, Short.MAX_VALUE).add(calendar));

But when i goahead and change my form design ,the previously added code disappears(i.e).add(calendar) disappears.

Please let me know if there is any other way to add components.
Thanks

Hi,
it would be gr8 if you can tell me where i can find good tutorial for pre-int/post-init code.

Thanks

[Riyad Kalla]

As you mentioned you can place customized initialization code into the initCOmponents method only by using the pre/post init properties of the component you are initializing. What I prefer to do is just put my custom init code in the constructor after the call to initComponents().

[infotechmadhu]

Hey thanks for the reply.
is it possible to add component to a panel outside initcomponent()?
i tried adding them as jPanel1.add(calendar);

Please let me know if there is any good tutorial for matisse form using myeclipse.so far i have just found one basic tutorial.

Thanks

is it possible to add component to a panel outside initcomponent()?

Yes absolutely. The initComponent is a special method that is regenerated from the form file each time you change/save. But if you want to write your own method, like customInitComponents() and add your custom code there, that’s perfectly fine. Just be sure to call it after initCOmponents since that sets up all the other components in the UI.

As far as the tutorial goes, we currently just provide the 1. Is there a specific thing you wanted to learn about? Maybe I can help?

Also we are starting to provide webinars for MyEclipse (Free), that M4M is a great topic we could cover for a future one.

Thanks..but when i try adding component it throws me an error.
i created a method called cutominit() and added my calendar component in a panel..but the calendar fails to pop up.
here is the code:Please let me know if i am doing anything wrong.

public class AddCalendar extends javax.swing.JFrame {
private JCalendar calendar;

/** Creates new form AddCalendar */
public AddCalendar() {
calendar = new JCalendar();
initComponents();
CustomInit();
}

private void CustomInit() {
// TODO Auto-generated method stub
jPanel1.add(calendar);
}

Sorry I can’t help here, besides not having working code to trouble shoot, I have no idea what the calendar’s behavior is coded to do. For example, do you have to set it’s size? mark it visible? give it a default date and time? etc. etc.

[infotechmadhu]

Basically just want an example to add dynamic components to panel outside initcomponents().
For now,i have added the calendat componet as custom component and it works fine…

Also it would be gr8 if you can give guide me to add pre-init/post-init and cutom code creation.
