my problem is that I have a lot of AbsolutePanels in GWT an they are drawn as if they were a TabLayoutPanel ( the GUI looks like a TabLayoutPanel, however, it is not one, it is made of a lot of AbsolutePanels ).
So, now I have the problem that as soon as a lot of tabs are opened they exceed the max. width of the AbsolutePanel and so they cannot be seen anymore nor can they be clicked or anything else.
So, is it somehow possible to add a ScrollBar to this AbsolutePanel in order to scroll back and forth?
I do not think it is a good idea to post any code because everything is being done programmatically. The only thing that I would need is an example of how to accomplish a scrollbar within an AbsolutePanel. This AbsolutePanel is of a fixed width!
Thank you very much for your help in advance.
Use CSS Overflow property.
You just need to set overflow: auto;.
It can be done programmatically:
panel.getElement().getStyle().setOverflow(Overflow.AUTO);
or with CSS style sheet:
.overflowAuto {
overflow: auto;
}
and
panel.addStyleName("overflowAuto");

I have a HorizontalPanel and I added two Buttons to it.
The HorizontalPanel is already as wide as its parent.
I want each Button to take a half of the HorizontalPanel. How can I do it programmatically?
Or maybe am I using the wrong panel? Any advice would be appreciated.
I tried setWidth("50%"). It looks strange. I also tried other panels e.g. FlowPanel. I just cannot figure it out...
Use setWidth("100%") instead of setWidth("50%") for both the Buttons and then add it to HorizontalPanel.
I am currently working with GWT and the SuggestBox.
The Suggestboxpopup is appearing behind the panel the Suggestbox is placed on. I am aware that there is an issue with the Suggestbox popup's z-index but I am looking to see if anyone has another solution other than hard-wiring the the z-index in the CSS.
The reason for this is the panel the suggest box is on has a Z-index helper which moves the panel to the front anytime it is clicked. While a super high z-index will resolve the issue i am wondering has anyone found a better solution which will allow the popup to move with the other widgets.
Yep, this is an known problem in SuggestBox which is in the issues list of GWT. It has been closed recently because of a lack of activity in the issue, you can put a comment to reopen it though.
I think it is not very important because no much apps need a suggest box on a popup.
I had the same issue in a project and I solved it with css as you suggest.
I need a scrollPanel with a verticalpanel and a tablayout panel inside it. Problem is, unless I specify the exact height of the tablayoutPanel, the tab content does not show. Any known fixes/ workarounds?
Not the answer you are looking for, but might spark an idea for another way to do this - what does it mean to scroll a tab panel? As soon as the user starts scrolling down, the tabs will no longer be visible to change tabs, user will always need to scroll all the way to the top to consider any other tab.
That said, any of the *LayoutPanel classes GWT has introduced that implement ProvidesResize, RequiresResize, etc need sizing to properly draw themselves and their content. This is why you are having the issue. These classes are designed to size their children, not to just consume as much space as those children require.
Closest I can suggest to a workaround (except for putting a ScrollPanel inside the TabLayoutPanel instead) would be to know the height of the current tab's contents, add to that the height of just the tabs themselves, and assign that as the height of the tabpanel. Not a very nice solution, but it might get you by.
once again I've got a question. Since I am using Google Web Toolkit (GWT) at work (along with Java Servlets), I am currently building some user interface with GWT (in Java).
I've got some trouble though. I am using a SplitLayoutPanel which contains a ScrollPanel on the left and another one on the right.
In the left ScrollPanel there's a VerticalPanel with several Labels, which differ in their width. What I want to accomplish, is: if the Label's text doesn't fit in one line, it should display as many characters as possible and have a "..." in the end, if it's not fully displayed.
I am about to add a CustomEvent EventHandler for the Label, which can be fired whenever the Label needs to change its content. Now the problem however is, that I'd need to fire the event whenever the ScrollPanel or its inner VerticalPanel is resized (by dragging the SplitLayoutPanel-Splitter).
Now the question: is it possible to override some sort of "onResize"-Event or at least "onMouseMove"-Event inside the VerticalPanel, so that I could fire the "changeLabelSize()"-method for each Label inside of this VerticalPanel?
How would I go about it? Thank you all for your time in advance! Please ask for anything unclear, so I can clarify it.
Best regards,
Igor.
This can be done easily with the CSS property text-overflow: ellipsis;.
Supported by IE7-, Safari and Konqueror.
And it can be emulated in Firefox.
This sounds like a pretty simple thing to do but I havent been able to find an easy way to do this. How do I create a panel with a title and a border which can contain my widgets? I have seen the SectionStack class which provides this. But I dont want to create a section stack.
Window can be added to a layout and drawn. But is it the only way or is there a container class that I am missing?
Also, how does one center things? Say a textfield and a button at the center of the page. How is this achieved?
If you are using a DynamicForm, you can give it a border and title with
form.setIsGroup(true);
form.setGroupTitle(title);
This actually works for Canvas, too (which is the superclass of most widgets and layouts in SmartGWT).
(I just had the same problem, and found this question, as well as the thread Is there a "titled Border" on the SmartGWT Forums, which gave this answer. I tried and it seems to work.)
To do form-related tasks, look into DynamicForm. To set the inputs in the form, you use setItems(Item...). A text field is a TextItem. You set it's title to control the label that SmartGWT will build. To get a title for the form, the best I've come up with is to use a container canvas that will contain both the title (probably a Label element) and the DynamicForm. To center the inputs, I believe you'd need to use setAlignment on the DynamicForm.
You could create an object that is actually a VLayout that contains a Label (the tile), has a border as you need and includes a Canvas (the generic stuff you want included).
In my experience, I noticed that very often I have a DynamicForm visible, so I just add a BlurbItem control to diplay the tile and a small explanation.
