setDelayMSec( -1 ) means that the message is displayed until the user clicks on the message box. Can I close to message box when user clicks anywhere outside?
Try to add a tag that uses the entire screen, with this:
public void createAndShowNotification(String caption, String description, Notification.Type type) {
description += "<span style=\"position:fixed;top:0;left:0;width:100%;height:100%\"></span>";
Notification notif = new Notification(caption, description, type, true);
notif.setDelayMsec(-1);
notif.show(Page.getCurrent());
}
No, when you use setDelayMSec(-1) then you have to click in the message box to close it.
If the user should be able to close it by clicking anywhere outside the box, you have to set a positive number.
Of course you can set a very high number, so that it does (almost) not autocloses...

We've created solution where user has a table with files, each entry has checkbox. He can select as many as he like and then click download button.
We are using such resource, it should allow dynamically download, depending on selected items
private StreamResource createResource(final IndexedContainer container) {
return new StreamResource(new StreamSource() {
#Override
public InputStream getStream() {
for (Object o : container.getItemIds()) {
CheckBox checkbox = (CheckBox) container.getItem(o).getItemProperty(C_CHECK_BOX).getValue();
if (checkbox.getValue()) {
selectedFiles.add(o);
}
}
// do some magic to get stream of selected files
}
}, "download.zip");
}
The problem is that only second and following click on button is giving expected restults.
It's turns out that FileDownoader is getting resource from server and then it is sending current status of component . It is the reason why first click is giving stale result.
Do you have any idea how to overcome this? Is it possible to force: first update component and then download the resource?
Many thanks

CheckBox in Vaadin is non-immediate by default, which means that it won't send a request to server when the checkbox is checked (or unchecked) on the browser. Immediate components send queued non-immediate events also to server but it seems that FileDownloader doesn't cause an event that would send non-immediate checkbox values to server.
The only thing you need to do is to set your checkboxes to be immediate when you create those:
checkBox.setImmediate(true);
FileDownloader will not suit your needs. As you can read in the documentation:
Download should be started directly when the user clicks e.g. a Button without going through a server-side click listener to avoid triggering security warnings in some browsers.
That means you cannot dynamically generate download.zip file determined by checkboxes values because that requires a trip to server.
You have at least 2 options. Either create new FileDownloader and generate new Resource download.zip every time user make changes to the checkboxes. Or you can add simple ClickListener to you Button with this line of code:
getUI().getPage().open(resource, "_blank", false);

There is also alternative solution to set checkBox.setImmediate(true); . It is possible to send current state of all components, just before click, instead of sending each checkBox change.
This solution is based on this answer: https://stackoverflow.com/a/30643199/1344546
You need to create file downloader button and hide it:
Button hiddenButton = new Button();
hiddenButton.setId(HIDDEN_ID);
hiddenButton.addStyleName("InvisibleButton");
StreamResource zipResource = createResource(container);
FileDownloader fd = new FileDownloader(zipResource);
fd.extend(hiddenButton);
Add css rule to your theme
.InvisibleButton {
display: none;
}
And then create another button, which 1st update state, and then click hidden button.
Button zipDownload = new Button("Download as ZIP file");
zipDownload.addClickListener(new Button.ClickListener() {
#Override
public void buttonClick(Button.ClickEvent event) {
Page.getCurrent().getJavaScript()
.execute(String.format("document.getElementById('%s').click();", HIDDEN_ID));
}
});
Morning - I'm having a little problem.
I have an autocomplete extender textbox where a user types in words and suggestions are provide. Should the term be rather generic, a list appears and the user can scroll up or down using the mouse wheel with no problems at all.
However, if the user attempts to click on the scroll bar and scroll through the list, it fires the textchanged event - which I don't want it to do.
This event should only fire once the user has actually selected the appropriate product from the list supplied.
I can set the autopost back of the text file off which has the desired effect but I do require the post back to be performed once the user selects a suggestion.
Does anyone know how I can get around this?
I managed to find a resolution.
Stick this in the page load event:
string contactPostBackFunction = null;
contactPostBackFunction = Page.ClientScript.GetPostBackEventReference(this.tbxProdAC, "", false);
string contactPostBackScript = null;
contactPostBackScript = string.Format("function postBackOnContactSelectedFromDropDown() {0} {1} {2}", "{", contactPostBackFunction, "}");
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "contactPostBackScript", contactPostBackScript, true);
And have this in your Autocomplete extender properties:
OnClientItemSelected="postBackOnContactSelectedFromDropDown"
I want that my api How to integrated RIM app with BlackBerry Address Book.For example:-send an SMS message by selecting a contact from BB native address, pressing the menu button, and choosing option Compose SMS via XYZ app like we have compose sms.
First you need to create a class, extend net.rim.blackberry.api.menuitem.ApplicationMenuItem and override the run(Object context) method.
This method will be called when the user clicks your menu-item and the context object will be of type javax.microedition.pim.Contact, so you can get all the relevant address information of the highlighted item.
Override toString() method to give your MenuItem a name, e.g.
public String toString() {
return "MyMenuItem";
}
Next you need to register you menu item. Create an auto-start, system-module application and call these methods:
ApplicationMenuItemRepository.getInstance().addMenuItem(
ApplicationMenuItemRepository.MENUITEM_ADDRESSBOOK_LIST, instanceOfYourApplicationMenuItem
);
ApplicationMenuItemRepository.getInstance().addMenuItem(
ApplicationMenuItemRepository.MENUITEM_ADDRESSCARD_VIEW, instanceOfYourApplicationMenuItem
);
The first call will register the menu item in the addressbook list view, the second one in the detail view (after an address has been opened).
Hope that helps!
I've got a shell tray icon with an attached context menu. The problem I'm having is that calling ShowDialog() from a context menu Clicked handler does not result in a modal dialog.
It's easy to reproduce this with a default C# project. Simply add the following code to the Form1.cs file:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
ToolStripMenuItem contextMenuShowMsg = new System.Windows.Forms.ToolStripMenuItem();
contextMenuShowMsg.Name = "contextMenuShowMsg";
contextMenuShowMsg.Text = "Show MessageBox...";
contextMenuShowMsg.Click += new System.EventHandler(this.contextMenuShowMsg_Click);
ContextMenuStrip contextMenuStrip = new System.Windows.Forms.ContextMenuStrip(this.components);
contextMenuStrip.Items.Add(contextMenuShowMsg);
NotifyIcon notifyIcon = new NotifyIcon();
notifyIcon.Text = "DlgTest";
notifyIcon.Icon = SystemIcons.Application;
notifyIcon.Visible = true;
notifyIcon.ContextMenuStrip = contextMenuStrip;
}
private void contextMenuShowMsg_Click(object sender, EventArgs e)
{
MessageBox.Show(this, "Test MessageBox");
}
If you build and run this, you will be able to get two message boxes on the screen by simply choosing the context menu item twice. Shouldn't this be modal? Replacing this with a call to ShowDialog() for another form results in the same non-modal behavior.
My best guess is that the NotifyIcon isn't specifically tied to the Form, as it would be in a typical Windows application. But I don't see any way of doing that.
Any ideas? Thanks in advance for any help!
I would suggest doing two things before you attempt to display a modal message box:
Make your icon's owner-window visible.
Give it focus.
Once you've done that, the this in the MessageBox.Show becomes a legal "modality parent".
Heck, it even makes more sense that the message box will be displayed on top of whatever program generated it, right? That way, the user has some context for what the message box is about!
You will need to keep track of activations of your system tray menu, and disable it when a dialog is open.
I have a screen that pops up on load with a print dialog using javascript.
I've just started using WatiN to test my application. This screen is the last step of the test.
What happens is sometimes WatiN closes IE before the dialog appears, sometimes it doesn't and the window hangs around. I have ie.Close() in the test TearDown but it still gets left open if the print dialog is showing.
What I'm trying to avoid is having the orphaned IE window. I want it to close all the time.
I looked up DialogHandlers and wrote this:
var printDialogHandler = new PrintDialogHandler(PrintDialogHandler.ButtonsEnum.Cancel);
ie.DialogWatcher.Add(printDialogHandler);
And placed it before the button click that links to the page, but nothing changed.
The examples I saw had code that would do something like:
someDialogHandler.WaitUntilExists() // I might have this function name wrong...
But PrintDialogHandler has no much member.
I initially wasn't trying to test that this dialog comes up (just that the page loads and checking some values on the page) but I guess it would be more complete to wait and test for the existence of the print dialog.
Not exactly sure about your situation, but we had a problem with a popup window that also displayed a print dialog box when loaded. Our main problem was that we forgot to create a new IE instance and attach it to the popup. Here is the working code:
btnCoverSheetPrint.Click(); //Clicking this button will open a new window and a print dialog
IE iePopup = IE.AttachToIE(Find.ByUrl(new Regex(".+_CoverPage.aspx"))); //Match url ending in "_CoverPage.aspx"
WatiN.Core.DialogHandlers.PrintDialogHandler pdhPopup = new WatiN.Core.DialogHandlers.PrintDialogHandler(WatiN.Core.DialogHandlers.PrintDialogHandler.ButtonsEnum.Cancel);
using (new WatiN.Core.DialogHandlers.UseDialogOnce(iePopup.DialogWatcher, pdhPopup)) //This will use the DialogHandler once and then remove it from the DialogWatcher
{
//At this point the popup window will be open, and the print dialog will be canceled
//Use the iePopup object to manage the new window in here.
}
iePopup.Close(); // Close the popup once we are done.
This worked for me:
private void Print_N_Email(Browser ie)
{
//Print and handle dialog.
ie.Div(Find.ById("ContentMenuLeft")).Link(Find.ByText(new Regex("Print.*"))).Click();//orig
Browser ie2 = Browser.AttachTo(typeof(IE), Find.ByUrl(new Regex(".*Print.*")));
System.Threading.Thread.Sleep(1000);
PrintDialogHandler pdh = new PrintDialogHandler(PrintDialogHandler.ButtonsEnum.Cancel);
new UseDialogOnce(ie2.DialogWatcher, pdh);
ie2.Close();
}
