Hi,

I have a Dialog class, which I use to upload files to a server. During the uploading process, I would like to display a progressbar (i.e. a rotating circle) over the dialog. This should...

This has nothing to do with the Groups, I guessed, that you use a base class within your Tree and you have to check its subclass instances with instanceof. So you have always nodes of the type of the...

I have used Orientation.HORIZONTAL only. In this case I have set the height and width with the following code:



@Override
protected void onResize(int width, int height) { ...

It seems to work with



Button btn = new SplitButton(); btn.addStyleName("btn-icon-print");


It is a little bit strange. The style name will be added to the "class" attribute of the element....

Hi,

I try to add a class name to a SplitButton, but it doesn't work:



Button btn = new SplitButton();
btn.getElement().addClassName("btn-icon-print");

Hm, it seems to be trivial.

I have looked into the GXT code to find out more about the rendering/attaching process. The TabPanel has a CardLayout, which renders the child widgets when the parent...

I have written a similar thing with a TreeGrid: http://smo-visittest.appspot.com/ It's only a prototype to show a workflow. Choose the trial xyz from the combobox and D&D the visits to another...

Hi,

I have a TabPanel which has multiple items. On every TabItem there are some fields. I have written a FormButtonBinding class, which monitors all the TabItems (which contain FormPanels). The...

Hm, I could get the StackTraceElement array within the listeners and look for FieldBinding.bind(). In such a case, I could prevent some data changes... Are there another ideas?

Hi,

I have a form, which uses field binding. Some fields of this form have change listeners to react on the user input (e.g. Radio buttons enable/disable/clear textfields or comboboxes). But I...

My ListField hasn't displayed the empty text, which I had set. I have created a subclass to get the correct behaviour. I use GXT 2.2.5.



public class DefaultListView<M extends ModelData>...

There could be a simpler solution, but I don't have enough experience to find another one. I'm also a pure Java programmer, JavaScript, CSS and HTML are terrible stuff and I try to avoid to work with...

I have created a subclass, which calls fields.clear() inside the constructor. So I can add new widgets to the underlying MultiField. In my application I need a horizontal dual list field, so I have...

Hi,

I have ModelData instances, which overwrite equals() and hashCode(). In the TreeGrid, it works fine, but I have problems with the SelectionModel. You use == and != to compare instances within...

Hi,

I need a label above the "from" and "to" list, but I only see the label of the MultiField object. Is it possible to display the sub-labels too?

Thank you
André

Define a CSS rule in your own CSS file and overwrite the default rule from gxt-all.css:

.x-tab-panel-body {
background-color: transparent;
}

André

Add your own CSS file to your index.html and redefine


.x-tab-panel-header {
border: none;
}

This is a problem with the XTemplate of the Combobox list. The name of the property foo.bar is added to the template. Is there a possibility to escape the dot, that the template will not interpret it...

Hi,

I have a ModelData, which uses a property name "foo.bar". Because of the nested property functionality, I have defined a constructor, which executes setAllowNestedValues(false). I have set the...

The image was named as *_16.png, so I thought it is 16x16, but it was 32x32. So the
IconHelper.createPath(String) always generate code for 16x16 images (see javadoc) and it seems that it returns...

I have found it: the image was bigger than 16x16. I use now another image and it is visible.

Embarrassing, embarrassing...

Hi,


I try to display an image within a Grid cell, but it doesn't work. First I have an Enum, which defines an image for every code:




public enum MyType {
X, Y, Z;

You're right. Sometimes it is simpler to copy the whole code instead to parameterize an existing class....:D

Btw, the missing questing was: How do I these things simpler...

I would add your treeGrid code into an Events.Show listener, which you could add to the MessageBox.getDialog().

André

Thank you, I have changed it and it works.
