I am using GXT for UI development. I have used HTML5 for Dragging file from Desktop to my application and upload it. But now i am having reverse requirement. I want to drag files from browser to desktop which will download the file to desktop.
I know that is possible in Chrome only. And had checked the below demo:
http://www.thecssninja.com/javascript/gmail-dragout
I had tried to implement the above code in my GXT application, but the issue is that i am using Editable Grid which is supporting DnD to TreePanel. Now when i drag from grid to Desktop i think its not capturing the browser event (may be i am wrong here).
Any idea, how it should be done?
Thanks.
Below is the small piece of code which i call after the Data had been inserted in Grid. All records are having the CSS class name as ".icon". The problem is that when i start to drag, the "dragstart" is not being called. Any suggestion?
NOTE: This code is working when i create Buttons, Labels, etc and making them draggable=true with other required parameters.
public static native void test(String id)/*-{
var files = $doc.querySelectorAll('.icon');
for (var i = 0, file; file = files[i]; ++i) {
file.addEventListener("dragstart",function(evt){
$wnd.alert("Drag Event started.. ");
evt.dataTransfer.setData("DownloadURL",this.dataset.downloadurl);
},false);
}
}-*/;
I used this, and it successully performs, no you should check some other place in your code.

I am using Winium + Java for automation testing of Windows application, and trying to access tool bar menu.
When I tried to detect elements using UI Automation Verify, I couldn't see child elements under tool bar element like below screenshot.
enter image description here
But my tool bar definitely has sub menu items like screenshot and I need to access them.
enter image description here
I tried below java code, but it didn't work
WebElement el = driver.findElement(By.id('59398'));
el.click();
WebElement child = el.findElement(By.name('Start'));
child.click();
when I tried
driver.findElement(By.name"Start').click();
it clicked my windows start menu, not my application's menu.
Is there any way to access items under this tool bar?
You can try use another UI Inspector
eg. UI SPY or Inspector.exe
Probably your ID is not a AutomationID (process id?)
You should find a main window (parent of your app) (Example for calc) and get a parameter like AutomationId, ClassName or Name
I see this is MFC application, and this is an app side MFC library problem. If you hover mouse over toolbar button using Inspect.exe, the info is available but you can't reach this button from the hierarchy (the buttons have no parent somehow). Possible workaround involves combined Win32 API and UI Automation approach:
get button rectangle using Win32 API (but there is no text).
use ElementFromPoint method of UI Automation API and get actual texts to choose the right button.
P.S. My suggestion is applicable for Java + Winium in theory. But I can't estimate the complexity because I'm not a Java expert. So below is Python solution.
We have plans to implemented this mixed way in pywinauto. See issue #413. It contains Python code sample how to do that. We've had no chance to integrate it yet.
from ctypes.wintypes import tagPOINT
import pywinauto
app = pywinauto.Application().start(r'.\apps\MFC_samples\RebarTest.exe')
menu_bar = app.RebarTest.MenuBar.wrapper_object()
point = menu_bar.button(0).rectangle().mid_point()
point = menu_bar.client_to_screen(point)
elem = pywinauto.uia_defines.IUIA().iuia.ElementFromPoint(tagPOINT(point[0], point[1]))
element = pywinauto.uia_element_info.UIAElementInfo(elem)
print(element.name)
I need to perform a key press combination on Selenium Chrome driver.
The action is not sending test to text box or clicking on a button.
I am actually not interested in sending keys to any specific web element.
For example, I would like to perform command+R (reload on Mac OS).
(Reloading is just an example for the explanation, not my ultimate goal)
My code is the following:
public static void keyPressCombnaiton() {
Actions action = new Actions(browser);
action.keyDown(Keys.COMMAND)
.sendKeys("r")
.keyUp(Keys.COMMAND)
.build()
.perform();
}
I have spend hours searching and trying only got no luck.
Any help is appreciated!
The WebDriver spec is element-focussed, and doesn't define any method to send keys to the window, the screen, to browser chrome - only to elements.
Use of the Selenium Actions class for Cmd-R works on my Mac in Firefox (45), but only when run in the foreground - and seemingly not at all in Chrome. Presumably this is down to differences in the implementations of the remote Keyboard implementation, which it's probably best not to rely upon.
The most efficient way and non-platform-specific way to request a page reload is using JavaScript:
((JavascriptExecutor) driver).executeScript("document.location.reload(true)");
However, JavaScript doesn't let you "just send keys".
The only other way is via the Java AWT Robot class:
Robot robot = new java.awt.Robot();
robot.keyPress(KeyEvent.VK_META); // See: http://stackoverflow.com/a/15419192/954442
robot.keyPress(KeyEvent.VK_R);
robot.keyRelease(KeyEvent.VK_R);
robot.keyRelease(KeyEvent.VK_META);
This "blindly" sends key combinations to whichever windows / components are on screen at the time, so if your browser window has been hidden or minimised, this will not work.
I have integrated the GWT application with Chrome packaged app with help of DirectLinkerinstaller like the code below:
public class CSPCompatibleLinker extends DirectInstallLinker {
#Override
protected String getJsInstallLocation(LinkerContext context) {
return "com/google/gwt/core/ext/linker/impl/installLocationMainWindow.js";
}
}
But now I want to call print function from Chrome packaged app. When I call window.print() it allows me to print current window, but I need to open a new separate window and print that.
Could you anyone please help me in this?
I can't answer anything about GWT or DirectLinkerinstaller, but here's an answer about Chrome Apps, assuming that's what you're asking about:
You use the chrome.app.window.create API to create a window. Then, you can call the print method for that window.
In my apps, I seldom want to print what's in a window, but rather something I've generated specifically for printing. For that, I create a PDF with jsPDF (Google it), which works well. Then I display the PDF in a window, and let the user print the PDF (or save it).
I have been asked by my friend to make an application for Chrome and it requires me to have context-sensitive menus as below:
I have never really made anything for Chrome before and I have a few questions regarding it:
I will have to develop a plug-in, right ?
If so, is there a specific set of rules I have to follow ?
I know I can use GWT to compile Java to JavaScript
3. This context sensitive menu is the same as JPopupMenu ?
The application I want to develop is simple:
Copy some text,
right-click, click on the context sensitive menu
apply simple Caesar's cipher to the text
open a new JFrame with JtextArea in it to display the encrypted text.
What you're creating is called an "extension", not a "plug-in". A browser extension is written using HTML, CSS and Javascript, and got access to APIs for direct interaction with the browser.
Plug-ins, on the other hand, are compiled binaries such as Flash and Java.
Drop the idea of using GWT for Chrome extensions. It makes development of the extension harder, not easier (open issue).
Especially because you'll find plenty of vanilla JavaScript examples and tutorials in the documentation and Stack Overflow.
You just have to know the relevant APIs:
Copy some text,
right-click, click on the context sensitive menu
Use chrome.contextMenus. There's no need to copy, the selected text is available in the callback (examples).
apply simple Caesar's cipher to the text
Create a JavaScript function to achieve this.
open a new JFrame with JtextArea in it to display the encrypted text.
Create a new window using chrome.windows.create. You could include an extra HTML page in your extension, and use the message passing APIs to populate the text field, but since you appear to be a complete newbie, I show a simple copy-paste method to create and populate this window:
function displayText(title, text) {
var escapeHTML = function(s) { return (s+'').replace(/</g, '<'); };
var style = '*{width:100%;height:100%;box-sizing:border-box}';
style += 'html,body{margin:0;padding:0;}';
style += 'textarea{display:block;}';
var html = '<!DOCTYPE html>';
html += '<html><head><title>';
html += escapeHTML(title);
html += '</title>';
html += '<style>' + style + '</style>';
html += '</head><body><textarea>';
html += escapeHTML(text);
html += '</body></html>'
var url = 'data:text/html,' + encodeURIComponent(html);
chrome.windows.create({
url: url,
focused: true
});
}

From within Java, I am opening an Excel file with the default file handler (MS Excel, in this case :-) ) using the method described in this stackoverflow question:
Desktop dt = Desktop.getDesktop();
dt.open(new File(filename));
However, the Excel program doesn't get the focus. Is there any easy way to do so?
Edit: There is a related stackoverflow question for C#, but I didn't find any similar Java method.
Edit 2: I've did some simple tests, and discovered that Excel starts and gets the focus whenever no instance of Excel is running. When Excel is already open en NOT minimized, the application doesn't get the focus. If instead the Excel Windows was minimized, the above code will trigger a maximization of the window and Excel getting the focus (or vice versa :-) ).
If you only care about Windows (implied in the question), you can change the way you invoke Excel: use "cmd start...".
I have been using this piece of code to launch Windows applications for some time now. Works every time. It relies on the file association in Windows to find the application. The launched application becomes the focused window on the desktop.
In your case, Excel should be associated with .xls, .csv and other typical extensions. If it is, Windows will launch Excel, passing your file to it.
Usage:
MyUtilClass.startApplication( "c:\\mydir\\myfile.csv", "my window title" );
file is the full path to the input file for Excel and title is the window title (the application may or may not take it - Excel changes the window title).
public static void startApplication( String file, String title )
{
try
{
Runtime.getRuntime().exec( new String[] { "cmd", "/c", "start", title, file } );
}
catch( Exception e )
{
System.out.println( e.getMessage() );
}
}
From a scala-program, which runs in the JVM too, I can open an application, and that get's the focus by default. (Tested with xUbuntu, which is a kind of Linux).
import java.awt.Desktop
val dt = Desktop.getDesktop ();
dt.open (new java.io.File ("euler166.svg"));
I can't say, whether this is specific for Linux, or maybe something else - however starting Inkscape in my example, excel in yours, may take a few seconds, while the user impatiently clicks in the javaprogram again, thereby claiming the cursor back. Did you check for that?
You could then change to the last application, at least on Linux and Windows with ALT-Tab aka Meta-Tab (again shown in scala code, which you can easily transform to javacode, I'm sure):
import java.awt.Robot
import java.awt.event._
val rob = new Robot ()
rob.keyPress (KeyEvent.VK_META)
rob.keyPress (KeyEvent.VK_TAB)
rob.keyRelease (KeyEvent.VK_TAB)
rob.keyRelease (KeyEvent.VK_META)
but unfortunately the unknown source off more trouble, also known as user, might do nothing, so switching would be the false thing to do. Maybe with a thread, which checks for a certain amount of time, whether the java-program has the focus, but it keeps a form of roulette, in an interactional environment, because the user may have a fast or slow machine, or change to a third application meanwhile, and so on. Maybe a hint before triggering the new app is the best you can do?
