This is a newbie question so forgive me but I'm confused.
Suppose, as a simple example, that I wish to have a GUI that has a button to add some component (say a file chooser widget) to the interface as many times as I want. (and maybe another button to remove the last if you wish to think more pragmatically). How would I design such a thing using glade? Is there any way to have the buttons "working" inside glade itself?
My guess is that I can only design the default interface and then I am manually responsible for the callbacks that will add and remove components. My GUI will however be static from within glade so I can only test it during runtime. Is that the basic idea?
You're correct, there is no way to test the callbacks in glade itself and you can only test it during runtime.

I want to use an AnyLogic’s controls such as Combo box and Radio Buttons for changing a parameter from the start. But now I can change the parameter only after the simulation is started. I want Anylogic at first show me the Radio Buttons and I choose the parameter and after that, I start the run.
Do you have any solutions?
This is what Experiment objects are for. Please learn how to use them via the tutorials and the help
Essentially, create parameters on Main and replicate them on experiment screens with variables and radio buttons linked to those. Then you can feed the user values to your Main using the experiment properties (section "Parameters").
Note that it is slightly different with cloud experiment setups.
To be clear i'm a newbie to GWT.I was looking around for samples to implement dynamic tabs, and found this link, http://www.java2s.com/Code/Java/GWT/AddingnewtabdynamicallyExtGWT.htm , in which they make use of GXT.But my question is,how can i implement dynamic views using UIBinder?.I want to implement something similar to browser tabs.Each newly created tab has a split panel view, whose content will be populated making a rpc request.My question is , how is the history mechanism handled when user switches between tabs?.Can anyone provide with samples?Thanks
You declare your TabLayoutPanel together with the initial/default tabs in UiBinder. Then you can add or remove tabs from this panel in your Java code.
I wanna customize cells in MonoTouch.Dialog.
For example make custom background in BoolElement and make custom image for this small bool thing that can be on or off, sorry forgot the name, or make custom disclosure indicator image in StringElement.
Is there simple way to do this without making own custom elements?
In some cases you'll need to create custom Element-derived types to customize cells. In other cases you will be able to add some custom code inside your application. FWIW I think it's cleaner to create your own everytime.
You can find a lot of examples in the Sample application that is available on github along with MonoTouch.Dialog (that includes having a custom background and totally owner-drawn elements).
There are also several questions (with answers) about common MonoTouch.Dialog customizations here on stackoverflow. Click on the monotouch.dialog tag and read them.
If you get stuck on a particular customization then don't hesitate to ask for help.
i'm new to j2me. how to set form elements (text field ,text box) width,font,alignment and other Gui related properties.
i tried to find solution for setting form background but no success. can you guide me
Firstly, J2ME is a very limited framework.
As far as I can remember if you are just using an item from the basic javax.microedition.lcdui package there is very limited styling available. It allows you to give directives on how to lay the item out on the screen and what the item's appearance mode will be.
An Item is not responsible for where it is placed and is down to the Screens layout management algorithm to place your item on the Screen. For example, the way Items are laid out on Forms and Lists differ based upon how the layout management works.
You can create your own customs items by extending CustomItem and implementing and overriding various functions to get the desired visual effect. This however is a lot of work
and the end result is not always very pleasing. You could also do the same by extending the Form class and overriding the paint methods to get your disered visual effect.
The best way to have control over form elements is to use one of the Widget like frameworks that exist and are built upon these basic J2ME classes. For example LWUIT and J2ME Polish allow you to style items in a very similar manner and layout Items using a CSS box inspired manner.
Although I have no used LWUIT so cannot vouch for it.
Is there a good way to create a form in VB6 that can easily be embedded inside other forms?
On a few occasions recently, I've wanted to design and code a Form object that I could plug into several other "parent" forms. My goal is to create a centralized piece of code for managing several UI components in a particular way, and then be able to use that (both the UI layout and the logic) in more than one place. I'm certainly willing to use code (rather than the Design View) to load the child form.
The best I've come up with so far is to pull all of the interesting logic for the child form into a Class Module, and have each parent form lay out the UI (in a Picture control, perhaps) and pass that Picture object into the class module. The class then knows how to operate on the picture, and it assumes that all its expected pieces have been laid out appropriately. This approach has several downsides, and I'd like something a bit more elegant.
Take a look at VB6 UserControls; I think they are exactly what you need. You can create a UserControl within your project, add controls and code to that control, and then insert it onto a form just like standard VB6 controls. I've used UserControls to share UI layouts on many occasions and it works great.
