I have a table with addresses. I have a button you can click which I want to open a google search for the address in a separate window. I have tried this code with BrowserWindowOpener.
getUI().getPage().open(url, "_blank")
and
BrowserWindowOpener opener = new BrowserWindowOpener(url);
opener.extend(googleBtn)
but both are appending my url to the current path. I want to simply run a search in google in a separate window. I'm sure this is much simpler than I'm making it. It sure should be, at least. Thanks.
Brimby, you were right with your second try. The BrowserWindowOpener extension is the way to go. You should use an ExternalResource instance with an absolute URL like this:
public class OpenGoogleUI extends UI {
#Override
protected void init(VaadinRequest request) {
BrowserWindowOpener extension = new BrowserWindowOpener(new ExternalResource("https://www.google.by/#q=vaadin"));
Button button = new Button("Open Google");
extension.extend(button);
setContent(button);
}
}
Try this:
// Hyperlink to a given URL
Link link = new Link("Google It",
new ExternalResource("https://www.google.by/#q=search+query"));
// Open the URL in a new window/tab
link.setTargetName("_blank");

on Vaadin 7 I have the working code :
private void gridAttachmentsClickItemEventAction(ItemClickEvent event) {
// blablabla some code to get the data from the repository
byte[] data = bibocoAttachmentResponseEntity.getBody().getContent();
StreamResource.StreamSource source = convertByteArrayToStreamResource(data);
String filename = "c:\\droppdf\\"
+"temp"+bibocoAttachmentResponseEntity.getBody().getFileName()+LocalDate.now().toString();
StreamResource resource = new StreamResource(source, filename);
resource.setMIMEType("application/pdf");
resource.getStream().setParameter("Content-Disposition", "attachment; filename=" + filename);
BrowserWindowOpener opener = new BrowserWindowOpener(resource);
opener.extend(btnAttachmentPreview);
}
When I click on a grid row, the data is collected from that grid
and code following on it gets the data byte[] from a repository by calling a service.
Afterwards, when the user clicks on btnAttachmentPreview a new browser tab opens
and shows the pdf (that's what's in the data byte[])
This works fine the first time, but when I select a new row in the grid,
the problem is that the second call does not set the listener to the button right.
It show the first data byte[] again in a new tab, not the current data ...
The method is accessed, the correct data[] has been loaded in the array the second time, I checked.
I believe the listener on the btnAttachmentPreview attached due the code
opener.extend(btnAttachmentPreview);
should be binned (empty'ed or nulled) first. But I have no reference to it as for as I can tell.
Problem is that I don't want to destroy the btnAttachmentPreview object.
(The btnAttachmentPreview is a global variable and is set to a layout that I may not change. I know, not nice, but it's a ancient product)
When I close the browser and restart and clicking another row, the right data byte[] is showed.
Anyone a clue ?
Any help appreciated
You can remove an extension using its remove() method, i.e. opener.remove();.
If you cannot easily structure your code to store a reference to the old opener so that you have it available when you want to add a new one, then you can use btnAttachmentPreview.getExtensions() to get a collection of all current extensions and then from that you can find the appropriate extension (if any) and call remove() on it.
I have a custom section, with a custom tree.
I'm having a bit of trouble understanding how you set the correct behavior when:
You click a node in your tree to edit it.
You click a menu item on a node like "Create"
In my solution I'm using the same view to edit and create a record.
In my tree this is how a node is generated.
var routeToView = "rewards/rewardsTree/editcampaign/campaign-" + campaign.Id.ToString();
var campaignNode = CreateTreeNode("campaign-" + campaign.Id.ToString(), id.Split('-')[1], queryStrings, campaign.CampaignName, "icon-folder color-yellow", true, routeToView);
This is producing the route I want: (the name of my html file is editcampaign.html) and it is also passing "campaign-6"
/umbraco#/rewards/rewardsTree/editcampaign/campaign-6
When a user clicks the create 'menu Item' on the node - I want to send them to the same URL but just with a diffrent Id for example:
umbraco#/rewards/rewardsTree/editcampaign/brand-1
and I don't want it to pop up out of the side
This is what I have tried so far:
//This finds the view, but it comes up in a dialog also how do I pass the Id (brand-1)
MenuItem mi = new MenuItem("editcampaign", "Create Campaign");
menuItemCollection.Items.Add(mi);
//Also Tried this finds puts a whole another umbraco UI inside a dialog
mi.LaunchDialogView("#rewards/rewardsTree/editcampaign/brand-1", "TITLE GOES HERE");
Can anyone point me to the fullest documentation for Menu's trees and navigation around the back office in general?
I believe there is an option to set view path on the "Create" menu item, which makes it open normally? Also, wouldn't it make more sense to have your path like /view/path/here/id ? Then when you create a new item just send 0 as id. Umbrangular on Github is a project with great examples of custom sections and views.
EDIT: Here's an example
protected override MenuItemCollection GetMenuForNode(string id, FormDataCollection queryStrings)
{
var menu = new MenuItemCollection();
MenuItem createCategory = new MenuItem("createcategory", "Create Category");
createCategory.AdditionalData.Add("ParentCategoryId", id);
createCategory.NavigateToRoute("/path/to/view/category/0");
createCategory.Icon = "add";
menu.Items.Add(createCategory);
return menu;
}
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
Pawel
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));
}
});
I have a BrowserField in my app, which works great. It intercept NavigationRequests to links on my website which go to external sites, and brings up a new windows to display those in the regular Browser, which also works great.
The problem I have is that if a user clicks a link to say "www.google.com", my app opens that up in a new browser, but also logs it into the BrowserHistory. So if they click back, away from google, they arrive back at my app, but then if they hit back again, the BrowserHistory would land them on the same page they were on (Because going back from Google doesn't move back in the history) I've tried to find a way to edit the BrowserField's BrowserHistory, but this doesn't seem possible. Short of creating my own class for logging the browsing history, is there anything I can do?
If I didn't do a good job explaining the problem, don't hesitate for clarification.
Thanks
One possible solution to this problem would be to keep track of the last inner URL visited before the current NavigationRequest URL. You could then check to see whether the link clicked is an outside link, as you already do, and if it is call this method:
updateHistory(String url, boolean isRedirect)
with the last URL before the outside link. Using your example this should overwrite "www.google.com" with the last inner URL before the outside link was clicked.
Here is some half pseudocode/half Java to illustrate my solution:
BrowserFieldHistory history = browserField.getHistory():
String lastInnerURL = "";
if navigationRequest is an outside link {
history.updateHistory(lastInnerURL, true);
// Handle loading of outer website
} else {
lastInnerURL = navigationRequest;
// Visit inner navigation request as normal
}
http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/browser/field2/BrowserFieldHistory.html#updateHistory(java.lang.String, boolean)
I had a similar but a little bit different issue. Special links in html content like device:smth are used to open barcode scanner, logout etc and I wanted them not to be saved in BrowserFieldHistory. I found in WebWork source code interesting workaround for that. All that you need is throw exception at the end like below:
public void handleNavigationRequest( BrowserFieldRequest request ) throws Exception {
if scheme equals to device {
// perform logout, open barcode scanner, etc
throw new Exception(); // this exception prevent saving history
} else {
// standard behavior
}
}
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.
