I have a page layout that contains a static header / footer, and 2 dynamic
portions (an action bar, and a scrollable content area).
I want my resulting page to resemble:
---HEADER--- (static)
---action-bar--- (dynamic, updated by whatever is in Content)
---content--- (dynamic, scrollable)
---FOOTER--- (static)
I have setup my main page layout like this:
AppTemplateView.java:
...
ActionBar actionBar = new ActionBar();
...
DockLayoutPanel masterLayout = new DockLayoutPanel(Unit.PX);
masterLayout.addNorth(buildHeaderPanel(), 53);
masterLayout.addNorth(actionBar, 48);
masterLayout.addSouth(buildFooterPanel(), 32);
ScrollPanel scrollPanel = new ScrollPanel();
scrollPanel.add(appPanel);
masterLayout.add(scrollPanel);
initWidget(masterLayout);
...
public void setActionBar(ActionBar newActionBar) {
this.actionBar = newActionBar; // What do I actually need to do
here???
}
I'm using native GWT no extensions. My app uses Activities and Places.
Initially the screen renders fine, but when I navigate to a different
view, the content area updates correctly, but the action-bar doesn't
change. I'd like to update the action-bar from within each view
dynamically. For example:
TestView.java:
public TestView(AppTemplateView template) {
ActionBar actionBar = new ActionBar();
// build up the custom action bar for this view. Add it to the
template
template.setActionBar(actionBar);
// and build up the actual content for this view.
VerticalPanel container = new VerticalPanel();
container.add(new Label("Content goes here..."));
initWidget(container);
}
What's the right way to replace the actionBar content in the template from
within one of my views? I've tried having actionBar in the template be a
SimplePanel, and from my setActionBar() method calling actionBar.clear();
actionBar.add(newActionBar); but it still didn't update in the browser.
Another way I thought was to call from within setActionBar(ActionBar
newActionBar):
Element el = masterLayout.getWidgetContainerElement(actionBar);
el.removeAllChildren();
el.appendChild(newActionBar);
this.actionBar = newActionBar;
But I'm not sure if that's even a valid approach.
Any suggestions?
