Java Forum / GUI / October 2005editor how to
Hi, I want to write my own editor (don't shoot I know there are good etitors) . Can somebody give me a hint which component I can use for my editor for example JPanel, JTextArea or ???. John > I want to write my own editor (don't shoot I know there are good etitors) . > Can somebody give me a hint which component I can use for my editor for > example JPanel, JTextArea or ???. What do you want to edit? I would recopmmend different components for plain text or bytecodes ((J)TextArea) than formatted text like RTF or HTML (JTextPane/JEditorPane). >> I want to write my own editor (don't shoot I know there are good etitors) >> .

You'd probably want a JFrame and a JScrollPane somewhere in there too. And maybe a JMenu, with "File->Save" and "File->Open" MenuItems. That would take you into JFileChooser territory.

We have, (as potential 'root' containers) (J)Applet, JWindow, JDialog, JOptionPane, internal frames (what are they called again?).. A lot of choices. I chose (quite wisely, by chance) to avoid the entire complications of the host containers. One step at a time. ;-) >>>>I want to write my own editor (don't shoot I know there are good >>>>etitors) .

One step at a > time. ;-) I'd actually imagine that the first step would be use a JFrame. I can't imagine the OP doing much with a JTextArea without a root container, and getting an empty window to show up somewhere on the screen is the GUI universe's equivalent of "Hello World". As for not using the alternatives, JFrame is probably the closest to what the OP wants, given that (s)he's writing a text editor, and that (s)he seems new to GUIs (and thus probably doesn't want to do anything too fancy for a first try). (J)Applet: Gotta teach the OP about signing. JWindow: Gotta teach the OP how to provide his/her own title bar and other decorators. JDialog: they're (usually) dependent on a Frame anyway, so you're supposed to have a JFrame involved with this solution. JOptionPane: uses a JDialog behind the scenes, so same rationale as above. The JInternalFrame might actually be suitable for the OP's project, but again it adds a bit of complication. Perhaps when the OP is ready to write his/her second text editor... - Oliver ... > I'd actually imagine that the first step would be use a JFrame.

Then we're talking 'Frame/TextArea'! It'll do plain text just fine. The AWT TextArea even has a built-in scrollbars, so no need for the JScrollPane. (And FileDialog is a lot easier to use than that damnable JFileChooser!) </(slightly) tongue in cheek> > The AWT TextArea even > has a built-in scrollbars, so no need for the JScrollPane. Seriously? It's been a long time since I've used AWT... BTW, are there any reasons (other than supporting clients running older version of Java) to use AWT these days? - Oliver >>The AWT TextArea even >>has a built-in scrollbars, so no need for the JScrollPane. > > Seriously? Sure. You can specify the scroll-bar behaviour in the constructor.. <http://java.sun.com/j2se/1.5.0/docs/api/java/awt/TextArea.html#TextArea(java.lan g.String,%20int,%20int,%20int)> >..It's been a long time since I've used AWT... I prefer to use Swing wherever practical (old VM's being the main problem). Whenever I do AWT I go to 'reach for..' that toolbar, or color chooser, or tabbed pane, or HTML rendering component, or.. only to curse and think how I will either implement it, or more often, redesign the app(let - usually) around it. > BTW, are there any reasons (other than supporting clients running older > version of Java) to use AWT these days? My main reason for mentioning AWT these days is usually to point out that most of the 'Swing' GUI building involves a lot of classes and packages in the 'AWT'. E.G. ..most of the layouts, some of the AWT GUI events and exceptions, classes for color/color spaces, images, DND, fonts, geometry and printing.. Noobs who get 'seduced' by Swing often fail to explore the sheer extent of what the AWT (in general) provides. Ultimately I feel it would have been better to separate the packages of the GUI components from the rest of the events, layouts, printing, images etcetera., but then.. maybe that's just me. > BTW, are there any reasons (other than supporting clients running older >version of Java) to use AWT these days? copy/paste works.

[quoted text clipped - 3 lines] > BTW, are there any reasons (other than supporting clients running older >version of Java) to use AWT these days? Support for native look and feel? Swing pluggable LookAndFeelS are quite good, but they're not native widgets, while the AWT widgets ought to have a native peer somewhere around, which will presumably fit into the native look and feel better than any pure Java component can do. At the very least, Swing implementations will lag behind the OS UI lokk and feel by a few months.
