I am a newbie at Igniton, and I am trying to advance from 0 to my first step.
I created a Named Query which is retrieving some rows and columns, and what I would like to achive is quite simple. Show all the values in a Vision table.
But as far as I can check, I can not replace column headers, or change the height of the row, meanwhile I can set the column width and the value sorting.
How can do this, and even more, where should I start to make this first step? I mean, I have not idea of Ignition.
If you mean, change the name, this is typically done with aliases in the SQL query. It can be done with scripting as well, but not so easily if it's a bound query. If you are referring to styling, this can be done with scripting in a power table's configureHeaderStyle extension function.
In case you haven't found it already, the row height for a power table can be manually changed in the Vision property editor, but the Auto Row Height property will need to be unchecked before any row height adjustments will be accepted.
This kind of subclasses, what means in terms of usability and which are the implications in the back?
I mean, I am just starting at Ignition, and I even don´t know what JIDE or the "AbstractVisionScrollPane" are related with.
In programming hierarchy, these are referred to as classes, and anything that can be invoked via these classes are referred to as methods. Looking at the documentation in both instances, these are both implementations of the Class AbstractVisionScrollPane.
Knowing this class information is useful for scripting because Java documentation is thorough and easy to read. If there is ever any question about a component class, or where to look for documentation, the type() statement can usually provide the necessary direction.
At the heart of virtually everything in Vision is the programming language Java. and regardless of what the component is, it seems like you can simply stick a J in front of the word, and find the documentation for Java's version online. For example, a table in Java is a Jtable and checkbox in Java is a JCheckbox. Consequently, at the heart of a regular table is a JTable. The JTable is quite versatile and scriptable, but inductive automation develops and extends the class to make common things already in place or easier to implement.
