gridbaglayout

问题 I am working on a GUI for a project at school. I am using a GridBagLayout in swing. I want to have a label indicating the input(a type of file @ x = 0, y = 0), followed by another label(the actual file name once selected @ x = 1, y = 0 ), followed by a browse button for a file chooser( @ x = 2, y = 0 ).

问题 I am kind of new to Java Programming and I am trying to make a window that contains two buttons and a text area, as seen in the image below. The problem I encountered though was positioning the components. I tried using GridLayout and separating the window into 9 rows and 16 cells, but then found I couldn't make components occupy more than a cell. I know I should be using GridBagLayout but I don't know how exactly. Help would be appreciated. :) 回答1: You have a number of choices. Instead of

问题 I've got a JFrame whose root JPanel is instantiated with a GridBagLayout . At runtime, the panel is populated with components based on some description, and the width, height and x,y coords are given in the description to be used with the gridwidth , gridheight , gridx and gridy fields in GridBagConstraints . The components themselves can be also be JPanel s with their own child components and GridBagConstraints , the GUI is described in a tree so Frame is populated recursively. The problem I

问题 I'm using GridBagLayout to place my GUI components by the following code, wanting the components lay one by one in a column, without any gaps : import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; public class TestGUI extends JFrame{ public TestGUI(){ JPanel bigPanel = new JPanel(new GridBagLayout()); JPanel panel_a = new JPanel(); JButton btnA = new JButton("button a"); panel_a.add(btnA); JPanel

问题 See below a simple test code using a GridBagLayout (2 rows, 2 component on row 0, 1 component on row 1). Although I have specified weighty to be 0.01 for first row and 1 for second row, the ratio on the screen looks more like 0.3 vs. 0.7. It seems that the height of the first row is resized so that the whole textarea fits in it. How can I reduce the height of the first row, so that the scroll bars of the JScrollPane will appear? public class Test { public static void main(String... args) {
