I am struggling with a gwt/gxt problem. I've been using Sencha ValueProvider for grids and similar for quite some time without any trouble. Now I want to create a Cell wich gets an additional ValueProvider to display the Tooltip. For example I have a column with CustomerNames and the Tooltip is supposed to display the customerNumber.
Unfortunately I can't figure out how the ValueProvider works internally. I know, that I somehow have to use the Path-Attribute but I still can't get the correct value to be displayed.
I would be very thankful for suggestions!

I have a function that generates a Dgrid and fills it with content which it receives from Javaside.
I tried to do dojo-css to handle this like here:
Style Dojox Grid Row depending on data
After this didn´t work I tried to work with Dojo.connect to change the color of the row when the grid is being built and filled.
After that didn´t work I tried to use dojo.on or dojo.aspect.after but since I am a total Newbie in Dojo I have no clue where you can intersect in the code and do theses things.
with a code like so :
require(["dojo/request/xhr","dojo/dom-form", "dojo/dom", "dojo/_base/array", "dojo/json",'dgrid/Grid','dgrid/Selection',"dijit/registry","dojo/_base/declare","dojo/domReady!"],
function(xhr,domForm,dom, array, json, grid, selection,registry, declare){
..... Here the grid and data is declared java function called
}.then(function(data, array, grid, selection,registry, declare){
.....Here the dgrid is filled
}
Where/when should i use Dojo.Connect , Dojo.on or Dojo.after?
I´ve spent mutiple days trying to figure this out but the program either stops working or ignores my changes.
The link you mention above is for dojox grid, which is different to dgrid. Here is the link to css styling for dgrid.
It won't answer your question though which is about changing a row color based on content. The way I do this is cell by cell, using a custom renderCell function.
Documentation on renderCell can be found here, and an example can be found here.
ps: a bit of caution. The learning curve for dojo 1.x is quite steep. When looking for documentation, make sure you get the latest possible (1.10). If you find a link which is about version 1.6 or less, be careful: many 1.6 and before features have been deprecated in version 1.7.
I've created a Java Application Project in Netbeans. This project has the main class JFrame form. There is, inter alia, Combo Box. I need to add a quadratic function to this Combobox. And I really don't want to use for squared anything like this
^2 .
I've thought, that function might be represented by ,for example, .png file.(Like setting icon of buttons).
Is it possible to add a picture to the model of Combo Box?
Can be model of Combobox different than String?
Or any idea, how to add a function to the Combo Box without ^ or _ ?
I have this idea for few days, but I really don't know how to solve this.
The short answer is "yes".
The responsibility for displaying the value in the combo box comes down to the ListCellRenderer
Take a look at How to use Combo Boxes for details and Providing a Custom Renderer for specifics
Image from How to use Combo Boxes trail
Of course, how you achieve this is entirely up to you. I would encourage you to put something easily identifiable in the model and then let the renderer figure out how to render it. This is kind of important as you will need to know what the user has selected and identify it at some stage, and an Image might not be the best solution for this.
I know this question has been asked before on S.O. and other websites but I haven't found a definite answer -- most of them say its not easily done but I wanted to make sure that was the final verdict.
Here's my situation:
I'm testing a website that is using Highcharts (http://www.highcharts.com) using Selenium WebDriver (Java).
I basically want to grab the information that is displayed in a small tooltip pop-up that appears when you hover your mouse over each datapoint on the Highchart's line graph.
Looking at the web page's HTML code, I noticed there is <g class="highcharts-tooltip".... I also noticed that, as you move your mouse, the (X,Y) values in ...transform="translate(X,Y)"> change, which then changes the information displayed in the tool tip.
Knowing this, my approach would be to somehow grab all the (X,Y) values and plug them into the transform fields and grab the tooltip data. But I don't know how to programmatically grab all the (X,Y) values through Selenium.
Has anyone tackles this issue in the past or has a better way to grab the necessary information?
I started creating a library to work with HighCharts, what I currently have is available here:
https://github.com/Ardesco/Powder-Monkey/tree/master/src/main/java/com/lazerycode/selenium/graphs
It's quite hard to provide a generic library that deals with HighCharts as the customisation options on the individual charts can modify the SVG markup quite a bit. Hopefully the above will help to a degree.
As I do more it will be updated.
The Line Charts have to have a background to work. If the chart is created with .setBackgroundColour(null), then the "rect" is not added to the html.
I was able to to add the background colour back in set to the body background colour. However I'll try and figure out a way of doing it without the "rect".
I'm currently learning the adf framework, and while doing this I found myself in a situation I am not able to solve.
I have a tree component that works fine. I also have different forms, corresponding to different levels of the tree. Rather than having all of the forms visible at one time, I would like to only show the one that corresponds to the selected item in the tree.
To solve this, I created af:switcher, created facets and moved the forms there. Here is where I am lost, how do I tell the switcher to change the form? I tried to link them together using the facetName on the switcher, but no success. I suspect I did not link the right thing there, but I could not find anything helpful from the tree either! I assume it has something to do with the selectionListener and a bean, but I could not figure out a way to do this. Any clues?

I've got a blocking problem with the sorting functionality of a JTable; this made stall the development of the spare time open source project for 4 months now. Hope to be pointed into the right direction here.
Context: I'm working on extending the functionality of the ps3mediaserver to add a media library with pms-mlx. The UI of the media server has been done using swing.
Problem: When clicking on a column header in the JTable, a seemingly random column gets sorted instead of the one having been clicked.
Current implementation: Here's the description of the different components and classes being used for the implementation:
ETable: As alternate row colours aren't supported by default in the JTable, I've switched to the ETable extending the JTable. Source comes from here
FileDisplayTable: This is the class creating the table. In the init() method, the sorting is being enabled with 'table.setAutoCreateRowSorter(true);'
FileDisplayTableCellRenderer: Exists to always align cell content on the left
FileDisplayTableColumnModel: Does some mapping between internal types and column names
FileDisplayTableAdapter: This class implements com.jgoodies.binding.adapter.AbstractTableAdapter to map the objects with the table columns.
Possible solutions:
Preferably, I'd like to keep the current implementation and figure out how to correct the sorting, but I doubt someone can help me out with that!? Additionally their are some bits of code I had to add because of strange behaviours; they're commented in the code
The alternate option would be to change the JTable for another control altogether. I've made some research but didn't find the solution I was hoping for. The constraints are that
it must be embeddable in a swing UI
preferably it should support data bindings
support alternate row colours
row sorting
At some point it will be possible to open an editing dialogue, where the content of the row has to be retrieved, can be edited and when saved the row has to be updated.
Before reworking the entire thing I'd like to be sure the component will be able to handle all I want to do with it.
I'm more used to create GUIs using .NET in Visual Studio. It's quite different and a lot more difficult to do the same with swing. Please show me I'm wrong :)
[edit] If someone is willing to reproduce the problem, either get the source or the binaries, launch the application, navigate to the media library tab. In the Genral section import some videos by adding some video files. Go to the library section, click on apply to refresh the list and try to sort the table.
It may be useful to know that JTable columns can be dragged by the user. As a result, the view (JTable or a subclass) and model (an implementation of TableModel) may have different column numbers. Similarly, a RowSorter may affect the order or number of rows in the view as compared to the model. The related conversion methods are mentioned in How to Use Tables: Sorting and Filtering. In particular: "When using a sorter, always remember to translate cell coordinates."
Addendum: As an alternative, consider org.netbeans.swing.etable.ETable or it's subclass org.netbeans.swing.outline.Outline, depicted here.
