I have an plugin that displays a composite with a horizontal scrolled bar. I can't figure out how to get GridLayout() to position each widget one row, one after another. If the number of widgets exceed the composite width, you should be able to scroll right to see the rest of the widgets. The horizontal scroll bar appears, but has no ...
Is it possible to create a virtual composite using SWT, i.e. one could scroll horizontally or vertically beyond the maximum display area of the composite? I want the length and height of my widgets (images) to stay constant regardless what size the composite is changed to. If there are 50 images to display and only 10 can be viewed at ...
I've created composite indexes (indices for you mathematical folk) on tables before with an assumption of how they worked. I was just curious if my assumption is correct or not. I assume that when you list the order of columns for the index, you are also specifying how the indexes will be grouped. For instance, if you have columns a, b,...
Hi, I need to customize the column names for composite foreign keys in GORM, and I didn't find any document that shows how to do it. I know how to customize PK columns, and how to customize a single-column FK, but not multi-column FK. Is it possible at all? Thanks. ...
Hi, I have an Eclipse plugin that displays a view. What I want to do is display n images in the view in a single row with a centered label under each image. I want to view to be scrollable.

Hi, I'm just starting to use the composite application libraries for WPF. In my shell I have a region in a tabcontrol that is used to display different types of views.

I have a composite primary key, which together turns out to be rather large (~2000 bytes). I have no performance considerations, I just would like a primary key to enforce uniqueness. MySql doesn't like long primary keys. Is there a way around this? Perhaps to only enforce uniqueness, without building an index? I wouldn't want to use A...
Hello everybody, i have a problem related to the design of a composite structure. I have an Expression abstract class that describes a generic mathematical expression.

I have a composite WPF application. In one of my modules I want to make a wizard and have the steps show up in a region so I can switch between the steps easier. Originally I had this wizard showing up in a tab region and the nested region worked fine. Now I want to make it into a modal dialog box, but after I open it the inner region ne...

I am designing a laboratory database. Several products, samples, etc are identified by a composite number with multiple parts which indicate different values such as: origin, date, type, id today, etc. Examples of composite numbers might include a driver's license number (X44-555-3434), lot number (XBR-A26-500-2). How should composite...
