First question.. I am trying to concat several strings into one long string with carriage returns after each entry. That String is then placed inside a text box. Right now, when I render my textbox, the String is all one long line. I don't understand why. Code:
if (e.getSource()== btnSelect)
{
String chosen = "";
if (cb1.isSelected())
chosen = chosen + "" + cb1.getText() + "\r\n";
if (cb2.isSelected())
chosen = chosen + "" + cb2.getText() + "\r\n";
if (cb3.isSelected())
chosen = chosen + "" + cb3.getText() + "\r\n";
if (cb4.isSelected())
chosen = chosen + "" + cb4.getText() + "\r\n";
cb1.setVisible(false);
cb2.setVisible(false);
cb3.setVisible(false);
cb4.setVisible(false);
pack();
btnSelect.setVisible (false);
btnOK.setVisible(true);
message.setText("Enter your text message");
textMessage.setVisible(true);
txtChosen.setSize(100,500);
txtChosen.setVisible(true);
txtChosen.setText(chosen);
}
This JDialog box has components that come and go. Maybe I am doing it all wrong. But the Window doesn't have room for the new components after the user selects their recipients, even though I called the pack() method. This is all experimentation on my part, and I am out of time, I need to wrap this up and turn it in. I will take away the text window if I have to, but I'd rather not since I spent all day working on it.
How can I resize my window to hold the new components? I tried calling setSize(), but it didn't work. Here is the code, I know I need to clean it up a bit.. thank you!!
