Hi,
i have created a small view in Eclipse 3.0
public class HelloWorldView extends ViewPart {
it has two Text controls and a push button.
Now i want to save the data typed in these text fields into a file on
click of the button.
I used the button.addSelectionListener() method which does capture the
button click but i do not know how to access the values of other fields in
the view.
I tried creating my own selection listener class
class OkSelectionListener extends SelectionAdapter{
and then passing the Scrolled form instance
OkSelectionListener(ScrolledForm f){
form=f;
}
and then accessed the controls using
Control[] c=form.getBody().getChildren();
but i am not able to get the text value
the second problem with this is that form values would not be captured on
click..
Please help!!

Hi,
(without knowing how a ViewPart works in Eclipse) You have created the
Text controls somewhere. So you should have a reference to them. Then
just use myText.getText(). Or did I miss something?
Hope that helped,

FormToolkit toolkit=new FormToolkit(parent.getDisplay());

GridLayout layout=new GridLayout(2,false);
form.getBody().setLayout(layout);
Hyperlink link=toolkit.createHyperlink(form.getBody(),"I want a
click", SWT.WRAP);
GridData gd=new GridData();
gd.horizontalSpan=2;
link.setLayoutData(gd);
link.addHyperlinkListener(new HyperlinkAdapter(){
public void linkActivated(HyperlinkEvent e){
System.out.println("HyperLink Was Activated");
}
});
Label label1=toolkit.createLabel(form.getBody(), "Input Feild1 :
");
Text text1=toolkit.createText(form.getBody(),"Default Text1");
text1.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
Label label2=toolkit.createLabel(form.getBody(), "Input Feild2 :
");
Text text2=new Text(form.getBody(),SWT.RIGHT);
toolkit.adapt(text2,true,true);
text2.setText("475");
text2.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
text2.setData(FormToolkit.KEY_DRAW_BORDER,FormToolkit.TREE_B ORDER);
Button button=toolkit.createButton(form.getBody(),"Ok
Button",SWT.PUSH);
/*******PROBLEM AREA****/
SelectionListener sl=(SelectionListener)new
OkSelectionListener(form);
button.addSelectionListener(sl);
gd=new GridData();
gd.horizontalSpan=2;
button.setLayoutData(gd);
toolkit.paintBordersFor(form.getBody());
}
public void setFocus() {
}
How do i access the form controls(text in text boxes) in the
OkSelectionListener??

Hi Kruttik,
sorry, the problem is that I only know swt but not the eclipse
framework. I do not see your ok listener implementation. Here is how I
would do it:
final Text text1 = toolkit.createText(
form.getBody(),"Default Text1");
final Text text2 = new Text(parent, SWT.SOMESTYLE);
final Button but = toolkit.createButton(
form.getBody(),"Ok Button",SWT.PUSH);
but.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e)
{
System.out.println(text1.getText());
}
});
Note that the control variables are final so that you can access them
from within the listener.
Hope that helped,
Friederich

Hello
Just for your information: According to the "Eclipse UI Guidelines"
"Modifications made in a view should be saved immediately" whereas
"Modifications made in an editor follow an open-save-close lifecycle".
URL: http://www.eclipse.org/articles/Article-UI-Guidelines/
Guidelines: 1.2, 1.3, 6.1, 6.2, 7.1, 7.2
