I am creating a tree structure in RCP application. I want to able to create a pop up menu. I have been able to create a dummy menu item.
final Menu treeMenu = new Menu(check.getShell(), SWT.POP_UP);
MenuItem item = new MenuItem(treeMenu, SWT.PUSH);
item.setText("Open");
item.addSelectionListener(new SelectionListener() {
#Override
public void widgetSelected(SelectionEvent e) {
System.out.println("CAme in Open");
}
#Override
public void widgetDefaultSelected(SelectionEvent e) {
// TODO Auto-generated method stub
}
});
check.setMenu(treeMenu);
this menu however does not recognize the node details. I want something that can obtain information about the node which we have opened context menu on.
If you are using a TreeViewer (or TableViewer) just get the current selection:
IStructuredSelection sel = (IStructuredSelection)treeViewer.getSelection();
Object selectedElement = sel.getFirstElement();
For a Tree use:
TreeItem [] selectedItems = tree.getSelection();

i am trying to make an app in Codename one where i want to create a handburger menu on the right side at the top of the screen and a back button on the left side, but cannot get it to work I know it can be done where you have a handburger menu on the left side and a button on the right side. I made a picture of how I want it to look like. The back button is added in paint and not through the code.
Picture of app example
below is the code that I have used to get the menu on the right side.
public class MainForm {
public static Form mainForm;
Command cmd_back, cmd_AboutTheApp;
private enum SideMenuMode {
SIDE, RIGHT_SIDE {
public String getCommandHint() {
return SideMenuBar.COMMAND_PLACEMENT_VALUE_RIGHT;
}
};
public String getCommandHint() {
return null;
}
public void updateCommand(Command c) {
String h = getCommandHint();
if(h == null) {
return;
}
c.putClientProperty(SideMenuBar.COMMAND_PLACEMENT_KEY, h);
}
};
SideMenuMode mode = SideMenuMode.RIGHT_SIDE;
public void init(Object context) {
theme = UIManager.initFirstTheme("/theme");
UIManager.getInstance().setThemeProps(theme.getTheme theme.getThemeResourceNames()[0]));
UIManager.getInstance().getLookAndFeel().setMenuBarClass(SideMenuBar.class);
Display.getInstance().setCommandBehavior(Display.COMMAND_BEHAVIOR_SIDE_NAVIGATION);
}
public void start() {
if(mainForm != null){
mainForm.show();
return;
}
mainForm = new Form();
mainForm.setTitleComponent(title);
mainForm.setLayout(new BorderLayout());
addCommands(mainForm);
}
private void addCommands(Form f){
cmd_Back = new Command("Back");
final Button btn_Back = new Button("Back");
cmd_Back.putClientProperty("TitleCommand", btn_Back);
btn_BackButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
//do some thing
}
});
cmd_AboutTheApp = new Command("About the app");
final Button btn_AboutTheApp = new Button("About the app");
cmd_AboutTheApp.putClientProperty("SideComponent", btn_AboutTheApp);
btn_AboutTheApp.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
//do some thing
}
});
mode.updateCommand(cmd_Back);
f.addCommand(cmd_Back);
mode.updateCommand(cmd_AboutTheApp);
f.addCommand(cmd_AboutTheApp);
}
}
if I move the back button so that it is added after AboutTheApp button then the back button is displayed on the right side of the screen but also to the right of the menu, which is also on the right side. I've tried a lot of different ways but none seems to be working
We supported a right side menu bar in the SideMenuBar but not in the Toolbar API. We support placing components/commands in the left/right side of the title area in the Toolbar API but not in the SideMenuBar.
I guess the solution is to add support for the right menu bar into the Toolbar API but I'm not sure what the complexities are for such a change.
I suggest filing an RFE in the issue tracker asking for this but it probably won't be soon as we are closing the features for 3.3 right now.
I have an app that does this. Search Google Play (or App Store) for "Torquepower Diesel Cummins Engine" app.
in the theme Constants I set my own rightSideMenuImage and rightSideMenuPressImage, but the default hamburger menu may be OK for you.
On the beforeXXXX of each form I do something like this:
super.beforePartNumberForm(f);
Toolbar tb = createToolbar(f);
createBackCommand(f, tb);
addHelpX(tb);
addViewCartX(tb);
addCallTorquepowerX(tb);
addReverseSwipe(f);
create the toolbar
Toolbar createToolbar(Form f) {
Toolbar tb = new Toolbar();
f.setToolBar(tb);
Label l = new Label();
l.setIcon(res.getImage("tpd_logoZZ.png"));
tb.setTitleComponent(l);
return tb;
}
create the back button
void createBackCommand(Form f, Toolbar tb) {
Command c = new Command("") {
#Override
public void actionPerformed(ActionEvent evt) {
back();
}
};
c.setIcon(res.getImage("black_left_arrow-512.png"));
c.setPressedIcon(res.getImage("grey_left_arrow-512.png"));
// MUST set this before adding to toolbar, else get null pointer
f.setBackCommand(c);
tb.addCommandToLeftBar(c);
}
add whatever commands are needed to the sidemenu
void addHelpX(Toolbar tb) {
Command c = new Command("Help") {
#Override
public void actionPerformed(ActionEvent evt) {
showForm("HelpForm", null);
}
};
c.putClientProperty(SideMenuBar.COMMAND_PLACEMENT_KEY, SideMenuBar.COMMAND_PLACEMENT_VALUE_RIGHT);
c.putClientProperty("SideComponent", new SideMenuItem(fetchResourceFile(), c.toString(), "very_basic_about.png"));
c.putClientProperty("Actionable", Boolean.TRUE);
tb.addCommandToSideMenu(c);
}
I use my own SideMenuItem which is:
public class SideMenuItem extends Button {
SideMenuItem() {
this("");
}
SideMenuItem(String s) {
super(s);
setUIID("SideMenuItem");
int h = Display.getInstance().convertToPixels(8, false);
setPreferredH(h);
}
SideMenuItem(Resources res, String s, String icon) {
super();
setIcon(res.getImage(icon));
setText(s);
setUIID("SideMenuItem");
int h = Display.getInstance().convertToPixels(8, false);
setPreferredH(h);
}
}
I'm trying to implement an Android style side menu and I'm having an issue implementing the rounded icon on top and labels below it before the sideCommands are added.
How do I implement this please?
You can use Toolbar API which allows you to add components to the Sidemenu.
Have a look at Flickr demo.
Instead of using tool.addCommandToSideMenu(Command) you should use tool.addComponentToSideMenu(yourComponent, CommandToPerform)
Example:
#Override
protected void beforeMain(Form f) {
//Store your commands before setting toolbar
List<Command> cmds = new ArrayList();
for (int i = 0; i < f.getCommandCount(); i++) {
cmds.add(f.getCommand(i));
}
Toolbar toolbar = new Toolbar();
f.setToolBar(toolbar);
Label lblTitle = new Label("My Form", "Title");
lblTitle.setEndsWith3Points(false);
toolbar.setTitleComponent(lblTitle);
// Use your stored commands after setting toolbar
for (Command cmd : cmds) {
toolbar.addCommandToSideMenu(cmd);
}
Container CustomContainer = ...
toolbar.addComponentToSideMenu(CustomContainer, new Command("") {
#Override
public void actionPerformed(ActionEvent evt) {
//What CustomContainer should do (if any)
}
});
f.revalidate();
}
I have created a register form (not using the designer).
On the form I have created numerous text fields as well as a button with ...
Button btnRegister = new Button();
btnRegister.setName("btnRegister");
btnRegister.setText("Register");
btnRegister.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
frmRegister_btnRegister(f);
}
});
f.addComponent(btnRegister);
My question is how do I reference the textfields in the function being called from the button action listener. Specifically I am trying to set up arguments to use for a network call using addArgument. When I used the designer I used find(ComponentName) but that is not available anymore.
private void frmRegister_btnRegister(Form f) {
// register new user
ConnectionRequest r = new ConnectionRequest();
r.setUrl(sUrlWebSvc);
r.setPost(true);
r.addArgument("Rest", "1"); // restaurant code
r.addArgument("Req", "Register"); // R = register
//r.addArgument("first_name", findTxtUsertName(c).getText());
// show spinning dialog while connecting
InfiniteProgress prog = new InfiniteProgress();
Dialog dlg = prog.showInifiniteBlocking();
r.setDisposeOnCompletion(dlg);
NetworkManager.getInstance().addToQueueAndWait(r);
//System.out.println(r.getResponseData());
}
Assuming its defined just above this line:
Button btnRegister = new Button();
As:
TextField txt =....
Just change it to:
final TextField txt =....
And then you can pass it (or its getText() string value) to:
btnRegister.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
frmRegister_btnRegister(f, txt);
}
});
Naturally you will need to update the signature of frmRegister_btnRegister to accept a text field or a string.
I have a control with textbox. After user input few lines of text and submit that by button then, for every line of text I need to show a childwindow with grid where user has to select some value.
Let's say that user inputs 5 lines of text with names of clients (one line one client name).
For every of them aften click Submit, he must select Salesperson from ChildWindow.
Of course now effect of my loop is opening 5 ChildWindows with the in the same time.
How can I do user get next ChildWindow only after choosing an element from Childwindow grid ?
Maybe your control could use a class that looks something like this.
public class SalesPersonSelector
{
private Queue<string> _clientNamesToProcess;
private Dictionary<string, SalesPerson> _selectedSalesPersons;
private Action<IDictionary<string, SalesPerson>> _onComplete;
private string _currentClientName;
public void ProcessNames(IEnumerable<string> clientNames, Action<IDictionary<string, SalesPerson>> onComplete)
{
this._clientNamesToProcess = new Queue<string>(clientNames);
this._selectedSalesPersons = new Dictionary<string, SalesPerson>();
this._onComplete = onComplete;
this.SelectSalespersonForNextClient();
}
private void SelectSalespersonForNextClient()
{
if (this._clientNamesToProcess.Any())
{
this._currentClientName = this._clientNamesToProcess.Dequeue();
ChildWindow childWindow = this.CreateChildWindow(this._currentClientName);
childWindow.Closed += new EventHandler(childWindow_Closed);
childWindow.Show();
}
else
{
this._onComplete(this._selectedSalesPersons);
}
}
private ChildWindow CreateChildWindow(string nextClientName)
{
// TODO: Create child window and give it access to the client name somehow.
throw new NotImplementedException();
}
private void childWindow_Closed(object sender, EventArgs e)
{
var salesPerson = this.GetSelectedSalesPersonFrom(sender as ChildWindow);
this._selectedSalesPersons.Add(this._currentClientName, salesPerson);
this.SelectSalespersonForNextClient();
}
private SalesPerson GetSelectedSalesPersonFrom(ChildWindow childWindow)
{
// TODO: Get the selected salesperson somehow.
throw new NotImplementedException();
}
}
Assuming your control has already split up the names from the TextBox into a list called "names", then you can do this:
var salesPersonSelector = new SalesPersonSelector();
salesPersonSelector.ProcessNames(names, selections =>
{
foreach (var selection in selections)
{
var clientName = selection.Key;
var salesPerson = selection.Value;
// TODO: Do something with this information.
}
});
I haven't tested this, but Visual Studio isn't giving me any red squiggly lines.
I am trying to make some small additions to some old java code that does not support swing. I need to add a small dialog that contains a panel which has a checkbox and a couple text fields. When the user clicks on the checkbox I want to disable or enable the checkboxes. This part seems to work well but the text fields are not properly getting redrawn. When I click the checkbox the fields do not appear to become enabled but if I then click on the panel or the text field you see that they are enabled (the opposite is also true, when I un-check the checkbox the fields still look enabled until you try and click on them and they become ghosted and do not become selected). I use the setEnabled(boolean) to set the status of the fields. I have tried calling repaint and validate on both the fields and the panel after changing the status and this does not seem to work. I have also tried to have the fields request focus and this did not work. Anyone have any other ideas?
//The class that contains all of this is of type Window
//Declaration of the components
private Panel _inputPanel;
private TextField min , max;
//This method adds to two text fields
public void addMinMaxtextFields(String min, String max) {
TextField minField = new TextField(min);
TextField maxField = new TextField(max);
this.min = minField;
this.max = maxField;
this.min.setEnabled(false);
this.max.setEnabled(false);
_inputPanel.add(minField);
_inputPanel.add(maxField);
}
//listener for the checkbox
public void itemStateChanged(ItemEvent e) {
Component[] components = _inputPanel.getComponents();
min.setEnabled(!min.isEnabled());
min.setVisible(true);
min.validate();
min.repaint();
_inputPanel.validate();
_inputPanel.repaint();
this.pack();
this.setSize(this.getWidth(), this.getHeight());
this.validate();
this.repaint();
/* do nothing */
}
You will need to call update(Graphics g) on Panel after setEnabled(boolean) is called.
