I won’t repeat all that Java source code here, but if you repeat the exact same example, and replace the INFORMATION_MESSAGE type with an ERROR_MESSAGE type, like this: This icon comes from the addition of the INFORMATION_MESSAGE argument to the showMessageDialog method. This results in the following message dialog:Īs you can see, this JOptionPane message dialog now includes a title, and also includes a new icon that wasn’t there before. "Problem writing to backup directory: '" + backupDir + "'.", However, adding a title also forces me to add a message type when I call the showMessageDialog method (as you'll see from the general syntax options available, shown later), so in this JOptionPane example I’ll choose the INFORMATION_MESSAGE type:
Taking this JOptionPane showMessageDialog example to the next level, in a real world application you want to display your message dialog with a title, so next I’ll add a title to the showMessageDialog method. "Problem writing to backup directory: '" + backupDir + "'.") show a joptionpane dialog using showMessageDialog JFrame frame = new JFrame("JOptionPane showMessageDialog example") Now looking at this as a more complete showMessageDialog example, here is the source code for a complete Java class that demonstrates a showMessageDialog example with a slightly more complex message: When you supply a JFrame reference, the dialog is centered on that JFrame, so this behavior can be slightly different. Note that when you supply a null argument like that, the JOptionPane dialog will be centered on the user’s screen. JOptionPane.showMessageDialog(null, "A basic JOptionPane message dialog")
If for some reason you don't have a reference to JFrame or JWindow instance, you can make that field null, and still display the identical JOptionPane dialog, as shown in this example: In that example my first argument to the JOptionPane showMessageDialog method is a frame object, which presumably is an instance of a JFrame. When this line of code is executed it will display the following message dialog: JOptionPane.showMessageDialog(frame, "A basic JOptionPane message dialog") Starting with a simple example, if you just want to show a JOptionPane dialog with a simple text message, all you need is one line of Java source code, like this: I’ll walk you through some JOptionPane examples here, starting with a simple example and then increasing the level of difficulty as I go on. I’ve been working with the Java JOptionPane showMessageDialog a lot lately, so I thought I’d create a page here with a number of showMessageDialog examples, sort of a JOptionPane reference page.

Windows shows "unhandled win32 exception in java.exe" dialog.Īttempting to debug the process in VisualStudio produces a more detailed message: tDisplayMode(.) is called to adjust the OpenGL context size to match the resized Canvas.Ĭrash happens immediately after tDisplayMode(.) is invoked.Maximizing the window does not cause a crash, but restoring window from maximized does. The window is resized by dragging a corner.A Display is created, with setResizable(true) and Canvas as a parent.Other Java versions may or may not be affected - I was only able to test these six. I discovered a crash-to-desktop that happens when the following conditions are met:
