Hi, I have this situation:
One wizard with two pages.
on firts page I let the user to select intems from a grid (Table Viewer), and have 2 combos that acts as filters.
on page 2 I let the user to use a file dialog to choose a file, where to export items selected in firt page.
I wnat to display to the user in the 2nd page the filters selected in the 1st page.
As I can see the two pages area instantited at wizard creation time
@Override
public void addPages() {
page1 = new ExportarEnsayosPage1(page2);
page2 = new ExportarEnsayosPage2(page1);
page1.setPageComplete(false);
page2.setPageComplete(false);
addPage(page1);
addPage(page2);
}
The problem is that I want to update Labels in the 2nd page, whenever the user camnge the selection in the combo.
I don't know how to access and fire setText() method on the Labels no the page 2 from the page 1 of the wizard.
I try several ways.
-passing the 2nd page as parameter to the 1st page.
-using getPage("paso2") method of the wizard ...
nothing works...
Any Idea ?
what i'm doing wrong !
I'm in eclipse 3.7, with java 1.5 !
Best Regards

What I did is:
make sure that page2 is instantiated befor creatin page1:
page2 = new ExportarEnsayosPage2();
page1 = new ExportarEnsayosPage1(page2);
en events in page 1, I call events on page 2, in this case page 2 is not null !!
private void actualizarPage2() {
//IWizard wizard = this.getWizard();
//ExportarEnsayosPage2 page2 = (ExportarEnsayosPage2) wizard.getPage("ExportarEnsayoPage2");
if (page2 != null) {
page2.actualizarLabelAnio(_Anio);
page2.setLabelLocalidad(_localidad.getDescripcion());
}
}
and finally:
in page 2 those method force the redraw and pack !
public void actualizarLabelAnio (String anio){
lblTxtanio.setText(anio);
lblTxtanio.redraw();
lblTxtanio.pack(true);
getWizard().getContainer().updateButtons();
}
public void setLabelLocalidad (String localidad){
lblTxtlocalidad.setText(localidad);
lblTxtlocalidad.redraw();
lblTxtlocalidad.pack(true);
getWizard().getContainer().updateButtons();
}
I don't know if they are redundant .... but i lost a hughe amount of time... so this is way it works !!
