Action listener not working
Hi
In the following piece of code TankPanel() is called to creates the JPanel SSVI_JPanel or GPSX_JPanel depending on the selected item in the JComboBox WasteWaterModel_JComboBox.
I have declared an action listener on the JComboBox in WasteWaterPanel(). In the bottom section of code that responds to the action I would like to remove the JPanel GPSX_JPanel and then call SSVI_ModelParameters(); to add SSVI_JPanel. My action listener is not working though as I cannot even print the statement.
Can anyone suggest why?
Thanks
public JPanel Tank_JPanels[] =new JPanel[3];
public JPanel WasteWater_JPanel, GPSX_JPanel, SSVI_JPanel;
String Models[] ={"GPSX","SSVI"};
public JComboBox WasteWaterModel_JComboBox =new JComboBox(Models);
publicvoid GPSX_ModelParameters()
{
GPSX_JPanel =new JPanel();
GPSX_JPanel.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createLineBorder(Color.gray),"GPSX Model Parameters"));
Tank_JPanels[2].add(GPSX_JPanel);
}
publicvoid SSVI_ModelParameters()
{
SSVI_JPanel =new JPanel();
SSVI_JPanel.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createLineBorder(Color.gray),"SSVI Model Parameters"));
Tank_JPanels[2].add(SSVI_JPanel);
}
publicvoid WasteWaterPanel()
{
if(typeBox.getSelectedItem().equals("Waste Water Treatment"))
{
Tank_JPanels[2] =new JPanel();
Tank_JPanels[2].setBorder(BorderFactory.createTitledBorder(
BorderFactory.createLineBorder(Color.gray),"Tank Property"));
WasteWater_JPanel =new JPanel();
WasteWater_JPanel.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createLineBorder(Color.gray),"Waste Water Model"));
Tank_JPanels[2].add(WasteWater_JPanel);
WasteWaterModel_JComboBox.addActionListener(new ActionListener(){
publicvoid actionPerformed(ActionEvent evt){
WasteWaterModel_JComboBox(evt);}
});
WasteWater_JPanel.add(WasteWaterModel_JComboBox);
}
}
publicvoid WasteWaterPanel()
{
if(typeBox.getSelectedItem().equals("Waste Water Treatment"))
{
Tank_JPanels[2] =new JPanel();
Tank_JPanels[2].setBorder(BorderFactory.createTitledBorder(
BorderFactory.createLineBorder(Color.gray),"Tank Property"));
WasteWater_JPanel =new JPanel();
WasteWater_JPanel.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createLineBorder(Color.gray),"Waste Water Model"));
Tank_JPanels[2].add(WasteWater_JPanel);
WasteWaterModel_JComboBox.addActionListener(new ActionListener(){
publicvoid actionPerformed(ActionEvent evt){
WasteWaterModel_JComboBox(evt);}
});
WasteWater_JPanel.add(WasteWaterModel_JComboBox);
}
}
public TankPanel(){
super();
WasteWaterPanel();
if(WasteWaterModel_JComboBox.getSelectedItem().equals("GPSX"))
{
GPSX_ModelParameters();
}
if(WasteWaterModel_JComboBox.getItemAt(0).equals("SSVI"))
{
SSVI_ModelParameters();
}
}
publicvoid WasteWaterModel_JComboBox(ActionEvent evt){
if(WasteWaterModel_JComboBox.getSelectedItem().equals("SSVI"))
{
System.out.println("THIS PRINTS IF ACTION LISTENER WORKING!");
WasteWater_JPanel.remove(GPSX_JPanel);
SSVI_ModelParameters();
WasteWater_JPanel.repaint();
}
}
