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;
}

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...

[by A.Rothe]

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...

[by A.Rothe]

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().

Thank you, I have changed it and it works.

I work on a Desktop-based application, the window handling awaits always Window references to add and remove the windows on a central point. So I have to override all x-tool-close listener and also I...

Hi,

I have seen in the code, that Window.initTools() is called during onRender(). Which is the earliest time, I can access Window.getHeader().getTools() and the call will not return an empty list?...

[by A.Rothe]

Hi,

how I can add an image like MessageBox.QUESTION to an existing instance of Dialog? I have to use Dialog, because I need as superclass Window and not Object.

Is that possible?
Thanks a lot...

Hi,

I have an instance-based access control system, which prevents to calculation of the total number of records for a query. To get this information I have to fetch all records from the database...

Hi,

How I can define my own algorithm to calculate the value of an aggregation row? I need some information from different columns of the grid, in example:

colA: boolean

Hi,

is it possible to set the red edge of an edited cell manually? I change a model and have to re-insert it into the store (see post...

[by A.Rothe]

It seems, that the following is a good workaround:

1. find the model within the store
2. save the index of the model
3. remove the model
4. change the model's properties
5. re-insert the model...

Try TreeStore.getRootItems() and TreeStore.getChildren(model, true) to build your own list. The method getModels() returns the same as getAllItems().

[by A.Rothe]

Hi,

I have overwritten hashCode() and equals() for subclasses of BaseTreeModel and BaseModelData. It seems, that a lot of methods within TreeGrid and TreeStore go wrong. Both classes hold some...

[by A.Rothe]

I think, in the API docs you can find, that store.getAllItems() returns a list of all models without any order...
