Hi, i have been stuck trying to figure out the following situation. I
have created a FormPanel that contains a few MutliFieldPanels (which
contain Textfields, ComboBoxes and Buttons), and a GridPanel. I
created my own classes for the GridPanel and MultiFieldPanel by
extending them. Then i add an instance of these classes to the
FormPanel, used to hold them all together. The problem is that I want
to add Records to the GridPanel when the onClick listener of a Button
inside a MultiFieldPanel is called, but i cannot access the GridPanel
store because i add it to the FormPanel with "this.". I am currently
accessing the GridPanel in the onClick of the Button by calling
findParentBy(String) but i find this to be a bad solution ... Can
anyone please suggest a better way of doing this, using callbacks or
something cleaner than what i have done ... thanks. The snippet below
shows how i add the elements to the FormPanel, and the issue i have in
accessing the GridPanel from the onClick listener in the
MultiFieldPanel:
public class FilterPanel extends FormPanel{
private FrameType frameType = FrameType.FILTER;
private Store filterCriteriaStore;
private String errorMessage;
public FilterPanel()
{
init();
}
///////////////////////////////////////////////
//create criteria panel
///////////////////////////////////////////////
private void init()
{
///////////////////////////////////////////////
//main panel to hold other elements
///////////////////////////////////////////////
this.setFrame(true);
this.setBorder(true);
//add criteria selection
this.add(new CriteriaSelector(frameType));
//add criteria table to hold applied criteria
this.add(new CriteriaTable(frameType));
}
CriteriaSelector extend MultiFieldPanel and CriteriaTable extends
GridPanel. I want to add Records to the CriteriaTable from the
onClickListener of a button inside the CriteriaSelector. any help
appreciated. thanks.
