I've a dialog box which I want dispose by from back command as well. But it is not happening. Why is it?
selectDialog = new Dialog();
selectDialog.showPacked(BorderLayout.CENTER, false);
selectDialog.setDisposeWhenPointerOutOfBounds(true);
//why doesn't following code dispose dialog box?
Command back = new Command("") {
public void actionPerformed(ActionEvent ev) {
if (selectDialog != null) {
System.out.println("beck");
selectDialog.dispose();
}
}
};
setBackCommand(back);
Instead of:
setBackCommand(back);
Use:
selectDialog.setBackCommand(back);

I have customized my form titlebar and added buttons to it. Is it possible to add a listener to one of the buttons to add command(s) an overflow menu and show it.
Yes, command/s can be added to overflow menu by using the following codes and actionPerformed is called when click on the command
Toolbar toolbar = new Toolbar();
f.setToolbar(toolbar);
toolbar.addCommandToOverflowMenu(new Command("Test") {
#Override
public void actionPerformed(ActionEvent evt) {
showForm("NewForm",null);
}
});
Please try this it displays overflow menu when you click on button.
void showOverFlow(final Form f) {
Toolbar toolbar = new Toolbar();
f.setToolBar(toolbar);
toolbar.addCommandToOverflowMenu(new Command("overflow"));
Button button = new Button("show menu");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if (f.getToolbar() != null) {
MenuBar mb = f.getToolbar().getMenuBar();
if (mb != null) {
mb.showMenu();
}
}
}
});
toolbar.addComponent(BorderLayout.WEST,button);
}
I have a wpf window that shows Bing map whith som bushpin on it,
The window is getting opened by button click in code behind.
Each time i click on the button, new window shows up with current new data.
How can i close the "allready" opened window and open the a new one with the new data, or maybe refresh the current opened window with the new data.
here is my code:
IList<object> rowsToExport = getRows();
BingMapWindow window = new BingMapWindow(rowsToExport);
// somthing like this
if(window.IsOpened)
window.Close;
window.show();
OR
if(window.IsOpened)
window.refresh();
Have you considered storing reference to that window outside method and just checking it for null?
BingMapWindow window;
private void CloseWindow()
{
if(window != null)
{
window.Close();
window = null;
}
}
private void OpenWindow(BingMapWindow window)
{
this.window = window;
this.window.Show();
}
private void ButtonHandler()
{
CloseWindow();
var bingWindow = new BingMapWindow();
OpenWindow(bingWindow);
}
I am following this exactly:
http://msdn.microsoft.com/en-us/library/ms185301.aspx
but can't get it to work. The form appears when I try and add my new item, but when I input text and click the button, nothing happens.
For posterity's sake here is my code:
The non-empty methods in the Wizard class which extends IWizard
public void RunStarted(object automationObject,
Dictionary<string, string> replacementsDictionary,
WizardRunKind runKind, object[] customParams)
{
try
{
// Display a form to the user. The form collects
// input for the custom message.
inputForm = new UserInputForm();
inputForm.ShowDialog();
customMessage = inputForm.get_CustomMessage();
// Add custom parameters.
replacementsDictionary.Add("$custommessage$",
customMessage);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
// This method is only called for item templates,
// not for project templates.
public bool ShouldAddProjectItem(string filePath)
{
return true;
}
The user input form code:
public partial class UserInputForm : Form
{
private string customMessage;
public UserInputForm()
{
InitializeComponent();
}
public string get_CustomMessage()
{
return customMessage;
}
private void button1_Click(object sender, EventArgs e)
{
customMessage = textBox1.Text;
this.Dispose();
}
}
And the button is indeed named button 1:
this.button1.Location = new System.Drawing.Point(200, 180);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(100, 40);
this.button1.TabIndex = 0;
this.button1.Text = "Click Me";
this.button1.UseVisualStyleBackColor = true;
So I don't have much experience with Windows Forms (do web apps), but I am following the directions on MSDN and it's pretty clear cut. Any suggestions? Can anyone else get this to work?
Okay I figured it out. I had to add the event handler in the form's constructor manually:
public UserInputForm()
{
InitializeComponent();
button1.Click += button1_Click;
}
Why this isn't in the documentation on MSDN boggles my mind.
If you use the WinForms designer mode to drag your button from the Toolbox, and then double-clicked the button in the designer view, it would have added the event handler and stubbed that Click method for you. Just FYI.
I have a WPF application in which on a click of a menu item a window is opened. If the same menu item is clicked again when the window is already open, it is opening a new window but I don't want a new window to be opened every time.
What I need is, if the window is already open, the same window should be focused not a new window.
//First we must create a object of type the new window we want the open.
NewWindowClass newWindow;
private void OpenNewWindow() {
//Check if the window wasn't created yet
if (newWindow == null)
{
//Instantiate the object and call the Open() method
newWindow= new NewWindowClass();
newWindow.Show();
//Add a event handler to set null our window object when it will be closed
newWindow.Closed += new EventHandler(newWindow_Closed);
}
//If the window was created and your window isn't active
//we call the method Activate to call the specific window to front
else if (newWindow != null && !newWindow.IsActive)
{
newWindow.Activate();
}
}
void newWindow_Closed(object sender, EventArgs e)
{
newWindow = null;
}
I think this solve your problem.
Att,
If your opened windows is used as simple dialog box you can use following code
window.ShowDialog();
when the dialog will show you cannot press any menu items unit you close this window
A rather brute force approach like this also works:
bool winTest = false;
foreach (Window w in Application.Current.Windows)
{
if (w is testWindow)
{
winTest = true;
w.Activate();
}
}
if (!winTest)
{
testWindow tw = new testWindow();
tw.Show();
}
You can create a field and check if it's set:
private Window _dialogue = null;
private void MaekWindowButton_Click(object sender, RoutedEventArgs e)
{
if (_dialogue == null)
{
Dialogue diag = new Dialogue();
_dialogue = diag;
diag.Closed += (s,_) => _dialogue = null; //Resets the field on close.
diag.Show();
}
else
{
_dialogue.Activate(); //Focuses window if it exists.
}
}
I have a simple message box in a WPF application that is launched as below:
private void Button_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("Howdy", "Howdy");
}
I can get white to click my button and launch the message box.
UISpy shows it as a child of my window I couldn't work out the method to access it.
How do I get access to my MessageBox to verify its contents?
Found it! The window class has a MessageBox method that does the trick:
var app = Application.Launch(#"c:\ApplicationPath.exe");
var window = app.GetWindow("Window1");
var helloButton = window.Get<Button>("Hello");
Assert.IsNotNull(helloButton);
helloButton.Click();
var messageBox = window.MessageBox("Howdy");
Assert.IsNotNull(messageBox);
Please try this
Window messageBox = window.MessageBox("");
var label = messageBox.Get<Label>(SearchCriteria.Indexed(0));
Assert.AreEqual("Hello",label.Text);
Contained in the White source code are some UI tests projects (to test White itself).
One of the test includes MessageBox tests, which includes a way to obtain the displayed message.
[TestFixture, WinFormCategory, WPFCategory]
public class MessageBoxTest : ControlsActionTest
{
[Test]
public void CloseMessageBoxTest()
{
window.Get<Button>("buttonLaunchesMessageBox").Click();
Window messageBox = window.MessageBox("Close Me");
var label = window.Get<Label>("65535");
Assert.AreEqual("Close Me", label.Text);
messageBox.Close();
}
[Test]
public void ClickButtonOnMessageBox()
{
window.Get<Button>("buttonLaunchesMessageBox").Click();
Window messageBox = window.MessageBox("Close Me");
messageBox.Get<Button>(SearchCriteria.ByText("OK")).Click();
}
}
Evidently, the label used to display the text message is owned by the window displaying the messagebox, and its primary identification is the max word value (65535).
window.MessageBox() is a good solution!!
But this method would stuck for a long time if the messagebox doesn't appear. Sometimes I want to check "Not Appearance" of a messagebox (Warning, Error, etc.). So I write a method to set the timeOut by threading.
[TestMethod]
public void TestMethod()
{
// arrange
var app = Application.Launch(#"c:\ApplicationPath.exe");
var targetWindow = app.GetWindow("Window1");
Button button = targetWindow.Get<Button>("Button");
// act
button.Click();
var actual = GetMessageBox(targetWindow, "Application Error", 1000L);
// assert
Assert.IsNotNull(actual); // I want to see the messagebox appears.
// Assert.IsNull(actual); // I don't want to see the messagebox apears.
}
private void GetMessageBox(Window targetWindow, string title, long timeOutInMillisecond)
{
Window window = null ;
Thread t = new Thread(delegate()
{
window = targetWindow.MessageBox(title);
});
t.Start();
long l = CurrentTimeMillis();
while (CurrentTimeMillis() - l <= timeOutInMillsecond) { }
if (window == null)
t.Abort();
return window;
}
