I designed two new components, I see it very convenient and useful, are the TDBSimpleComboBox and TDBSimpleListBox allow you to see the contents of a table, query, using the DataSource. Are set which fields you want to see what components and set the key value, all thanks to a few simple lines of code. Inside the zip file you download there is also a folder with examples. Tell me what you think and if there is useful, I need so many of the components so easy to use to interact with a db.
The only sin is in the component TDBSimpleComboBox run on Ubuntu 9.10 (other Linux systems I have not tested) because the source of the content of the combobox is different from the font of the combobox popup when I can figure out how to fix this bug that makes it impossible to align multiple fields within the combobox will update the package.
