use 80% of a row

[Leandro Coutinho]

Hi!

I have panel that has a scroll pane (with an editor pane) and a button. I would like that the scroll pane filled 80% of the panel. Is there a way to do this? How?

Check out weightx and weighty in GridBagLayout

[Michael Dunn]

another option is BorderLayout.

put everything else in a separate panel, then add that to EAST/WEST/NORTH or SOUTH,
giving it a preferredSize width or height (depending on where it is in the BorderLayout) equal to 20% of the frame's width or height,
then add the scrollpane to BorderLayout.CENTER, and it will take up the remaining 80%

Thank you.

I tried the below code but it didn't work. It is 50% for both. I'll try Michael Dunn's suggestion and give feedback.

                JPanel panelInput = new JPanel();
		panelInput.setLayout(new GridLayout());
		
		GridBagConstraints c = new GridBagConstraints();
		
		c.fill = GridBagConstraints.BOTH;
		
		c.gridwidth = 4;
		c.weightx = 1.0;
		
		final JEditorPane editorPaneInput = new JEditorPane();
		editorPaneInput.setSize(300, 100);
						
		JScrollPane scrollInput = new JScrollPane(editorPaneInput);
		panelInput.add(scrollInput, c);
		
		c.gridwidth = 1;
		c.weightx = 0.0;
		JButton btnSend = new JButton("Enviar");
		panelInput.add(btnSend, c);

No surprise as you're using GridLayout not the suggested GridBagLayout. There's a BIG difference.
