![]() This too can have an associated event handler of type ActionListener which is triggered when Enter is pressed when the text field is focused. JTextField is an area where a short text can be entered, on a single line. It's used by specifying an event handler of type ActionListener (see #Event Handlers) which is triggered when the button is clicked. This can have either a text or an image displayed on top. JLabel is a component used to display text or image in a container. This is particularly useful when reusing a panel. It is recommended not to place elements directly in a JFrame, but in a JPanel that is placed in a JFrame. It can be visible, changing the background color, the image model or having a border, or be invisible, only used for the hierarchy of the content. JPanel is a generic container that can hold other elements. For a more detailed description, read the Oracle tutorial. Next, we'll present the elements required for task 6. So, there is a hierarchy of components, each element called parent containing other sub-components called children. This is a JFrame containing the most used elements in Swing:Īll Swing objects, with the exception of class JFrame, inherit class which in turn inherits (indirectly) class. It's the element associated with the horizontal bar containing the icon, application name and the three buttons minimize, maximize and close: The main container class for GUI elements is. Here’s the code that generated the above example: Įxample control that spans the whole width.The package that contains the majority of classes for Swing applications is java.swing, some other other classes are used from the older package java.awt. But I should have a complete version of this in our next public build. (I will also add support for this stuff to the EditForm class when I get a chance).Īnyway: Some of this is still work in progress (FlowForm doesn’t yet have category support like the EditForm does, but I will add that in) as I am working in this for our Outlier customer. So this is pretty nifty as it further cuts down on the number of things that have to be added to the view and improves maintainability. When set, it is not necessary to add a or element for the label anymore, but you can just set the label property and a label will be rendered automatically. They support the mvvm:View.Label=”xxx” property. The flow form also supports some nice new things that will be added to other parts of the framework too. This behavior can be turned on and off with a property, btw. If only the “Existing” checkbox would have been moved to the next line, things would have been rather awkward, to say the least.Įventually of course, when the form gets too narrow, the individual checkboxes start to flow like this: So this creates a much nicer layout with both checkboxes moved to the next line with the matching “Facility Type” label. Note also how in the following example, both Facility Type checkboxes have been pushed to the next line, even though one of them would have still fit: Note that the flow form is smart about handling checkboxes and radio buttons, which tend to re-flow a bit different. ![]() When the form is resized, controls may flow to the next row (note how the Number field is pushed over to the next row, and all the textboxes left edges still line up properly): The flow form still does some smart things, such as making sure all the first labels in a row have an equal width. The basic idea behind the flow form is that controls are flowed in left-to-right until a line is full or a manual line break is encountered. Here’s an example of what a flow form looks like: Another, more recent addition, is FlowForm layout. One such example is the EditForm layout (see also: Automatic Layout and Elasticity).
