Re: DockPanel Question
Ah ok, It seems that is common practice then. I will do that, I was just wondering if there's a nicer way to do it. Thanks for your suggestions!

Re: DockPanel Question
Have you tried putting all the stuff you need to clear in a panel that you add/remove from the DockPanel areas? You could easily keep track of the one Panel in the area and might even be able to cache them.

DockPanel Question
So, I was working with a DockPanel, and I want to remove a Widget. Seems to only be two ways, remove teh Widget or remove the Widget by it's index. Is there a way to remove Widgets by their Direction? I feel there should be a DockPanel.clear(DockPanel.NORTH) or something to that effect. For example, I want to put GWT.Visualizations in the Center direction with the surrounding directions controlling which type of Visualization is in there. That means, I wont' know what is in there, it could be the default HTML giving directions for all I know. What's the best way to clear the Center(or any) direction before adding to it? Seems like a pretty useful thing that's missing from the API. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Dockpanel question
The easiest way is to add a panel to the centre - just a SimplePanel will do - and clear() and then add() to that.

Re: Dockpanel question
This seems to work fine!!! ty gregor One question about DockPanels. Is it possible to do sth like that? outer.remove(DockPanel.CENTER.widget) in case u arent sure about the panel u set in the center. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Dockpanel question
Hi Jake,
I think your problem is here:
tree.addTreeListener(new TreeListener(){
public void onTreeItemSelected(TreeItem item) {
ThirdMenu neo = new ThirdMenu(item.getText()); won't
work
}
public void onTreeItemStateChanged(TreeItem item) {
if (item.getState()){
// currChapter.setText(item.getText());
}
}
You have attached a first instance of ThirdMenu to outer where it
remains. You have instantiated a second instance of ThirdMenu but you
have not attached it to outer (or anything else), so it does not get
displayed. When you write Widget.add(Widget someWidget) you are
effectively attaching it to the DOM behind the scenes (starting off
with RootPanel.get.add(..)). To make it do so you would need to write:
public void onTreeItemSelected(TreeItem item) {
ThirdMenu neo = new ThirdMenu(item.getText());
outer.remove(new1);
outer.add(neo,DockPanel.CENTER);
}
Arguably a better strategy would be to make ThirdMenu a mutable and
update the same instance from the listener. If ThirdMenu was a Tree,
for example, you would probably have a method to build it in the first
place from some parameter. Then you can call Tree.clear() followed by
the build method when you need to update ThirdMenu. Also if you have
ThirdMenu implement TreeListener then it can be registered with
SecondMenu and therefore be notified of SecondMenu selections via the
Event model which is generally the best way to do it as it decouples
Second- and ThirdMenu.
regards
gregor

Re: Dockpanel question
I dont think that this is possible with DockPanel. You have to create a Vertical Panel , then calling Topmenu() and then a HorizontalPanel() with a Tree listner inside it so it will change the right side. If Dockpanel can do this , i m really curious to see how it is done. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Dockpanel question
Hello i m trying to make a page like the mail application.
What i want look like this one
---
|1 |
|-|
| ||
| ||
| 2 |3 |
| ||
| ||
||___|
1 and 2 are static but in 3 frame i want to be refreshed any time i m
pressing a treeItem from 2 menu.
This is how i m trying to make this happen.
First.java
private TopPanel topPanel = new TopPanel();
private SecondMenu new2 = new SecondMenu();
private ThirdMenu new1 = new ThirdMenu("example");
public void onModuleLoad() {
topPanel.setWidth("100%");
new2.setWidth("100%");
new1.setWidth("100%");
DockPanel outer = new DockPanel();
outer.add(topPanel, DockPanel.NORTH);
outer.add(new2, DockPanel.WEST);
outer.add(new1, DockPanel.CENTER);
outer.setWidth("100%");
outer.setSpacing(4);
RootPanel.get().add(outer);
By using this, it is created a page like the one i want
Inside the SecondMenu i have made a TreeListener which force the
ThirdMenu to be redisned again after a TreeItem is pressed. This the
code
SecondMenu.java
tree.addTreeListener(new TreeListener(){
public void onTreeItemSelected(TreeItem item) {
ThirdMenu neo = new ThirdMenu(item.getText());
}
public void onTreeItemStateChanged(TreeItem item) {
if (item.getState()){
// currChapter.setText(item.getText());
}
}
In the thirdmenu so far , i just print in the its region what user
parses.
However when i try to do that nothing happened. It seems that the menu
i created is a static one and nothing changes.
So indide the ThirdMenu i put this: RootPanel.get().clear(); and
then printing the argument
But the result is a blank page with no menus at all , neither Toppanel
nor secondmenu.
Any help?
