I don't want a fullscreen application, but I would like to start a Node-Webkit application maximized. Can this be done? I am guessing its something to do with package.json, but can't seem to find what needs to be done.
I don't think the manifest has an option to do that. Instead, call nw's Window.maximize() on startup. Something like:
// Load native UI library
var ngui = require('nw.gui');
// Get the current window
var nwin = ngui.Window.get();
Sometime later, in onload or some other point where you're ready to show the window:
onload = function() {
nwin.show();
nwin.maximize();
}
This is described in the node-webkit wiki. I don't think you can call maximize before showing the main window though (if it's hidden in manifest), but I haven't really dug into it.
You may want to consider saving the window position, from a UX standpoint. The wiki has an example for doing this.

I have a UWP application.
And i have a need to change locale on the fly, so i have this for language changing:
Windows.Globalization.ApplicationLanguages.PrimaryLanguageOverride = language.FourDigitCode;
ResourceContext.GetForViewIndependentUse().Reset();
ResourceContext.GetForCurrentView();
But there is a problem that system features language doesn't switch ( only after application relaunch ) how can i fix it?
Here is an example:
Now i run this code:
Windows.Globalization.ApplicationLanguages.PrimaryLanguageOverride = "lv-LV";
ResourceContext.GetForViewIndependentUse().Reset();
ResourceContext.GetForCurrentView();
The UI gets localized, but system features still remain unlocalized:
But when i restart the app, all is OK:
Any ideas how can i fix it?
I'm afraid there is no fix for this and what you've seen is by design. Ref Remarks of PrimaryLanguageOverride property:
When you set the PrimaryLanguageOverride, this is immediately reflected in the Languages property. However, this change may not take effect immediately on resources loaded in the app UI. To make sure the app responds to such changes, you can listen to the QualifierValues property on a default resource context and take whatever actions may be needed to reload resources. Those requirements may vary depending on the UI framework used by the app, and it may be necessary to restart the app.
For your scenario, a restart is needed. I'd suggest that you can add a tip to tell users to restart the app and also a button to close the app like what used in News App.
And to close the app, we can call Application.Exit method like the following.
Application.Current.Exit();
Maybe page reloading can fix it? Try to re-navigate to the same page.
Found the example below here.
//like this
private bool Reload(object param = null)
{
var type = Frame.CurrentSourcePageType;
Frame.Navigate(type, param);
Frame.BackStack.Remove(Frame.BackStack.Last());
}
// or like this
private bool Reload(object param = null)
{
var frame = Window.Current.Content as Frame;
frame.Navigate(frame.CurrentSourcePageType, param);
frame.BackStack.Remove(frame .BackStack.Last());
}
Question
How to use these private functions on other windows? It would be nice to have this knowledge back in the wild. I am specifically trying to get CGSOrderWindow and CGSSetWindowLevel to work.
I was trying in the direction of:
temporarily register as the dock and then register the dock as the dock again immediately afterwards
or
code injection into the Dock process per this comment:
Also, the author of the above project seems determined to make all core functionality available as a framework. It seems to be implemented as code injection into the Dock process.
Reason I know this is possible
I have been doing work on trying to setLevel on window of another app, and focus window of another app if focused. I am posting this again with the info I learned because from my searching online, I know this was done in the past, its just the knowledge is not publicly out there anymore. The sourceforge pages are no longer there. So I was wondering if you could help me make this information public again.
This is the topic I read that gave me this information - http://cocoadev.com/HowtoControlOtherAppsWindows
Here you see comments like:
You cannot control an another app's windows from a user-level process, unfortunately.
SlavaKarpenko
You can, Slava, you just need to register as the Dock. It might be possible to temporarily register as the dock and then register the dock as the dock again immediately afterwards, not sure. I think the call you'd be wanting to investigate as CoreDockRegisterDockOwner in HIServices.framework.
FinlayDobbie
You could also use APE or similar to do control the windows, or (as mentioned above) register as the Dock (look for the private APIs with Universal Connection in their name). Has anyone found a polite way of getting the Dock to give up its universal connection? The only way I can find is to force quit the Dock and grab the universal connection when it's not looking (which prevents the dock reloading).

There's an open source project up on sourceforge.net that looks much more like the window managers I've used on Unix boxes than Space.app (or Space.dock): http://wsmanager.sourceforge.net/

Verifying things work
This is what I learned, from the sources at bottom of this post, we see all these functions work with CGWindowIds, so how do I get that, this is how:
Get all windows with CGWindowListCopyWindowInfo. Then access each element from that array with CFArrayGetValueAtIndex and then get the CGWindowId with objectForKey:, kCGWindowNumber, and then integerValue.
Now if I try to focus or set level of a window that is OWNED by the app running the code, it works fantastic. For instance:
MY_TARGET_CGWINDOW_ID = 179;
rez_CGError = CGSOrderWindow(_CGSDefaultConnection, MY_TARGET_CGWINDOW_ID, kCGSOrderAbove, 0);
Will focus it, rez_CGError is 0. Even if the window is minimized, it is unminimized, without animation, and shown.
Now however, if I try this on a window of a different app we get some errors:
MY_TARGET_CGWINDOW_ID_of_other_app = 40;
rez_CGError = CGSOrderWindow(_CGSDefaultConnection, MY_TARGET_CGWINDOW_ID_of_other_app, kCGSOrderAbove, 0);
This fails and rez_CGError is 1000, which I suspect means "cid (CGSConnection) used does not have permission to modify target window". The same happens if I first do [app activateWithOptions: (NSApplicationActivateIgnoringOtherApps | NSApplicationActivateAllWindows)] before making the call above.
So I first get the cid of that owning window like this:
var rez_CGError = CGSGetWindowOwner(_CGSDefaultConnection, MY_TARGET_CGWINDOW_ID_of_other_app, &ownerCid);
This works good and I get ownerCid is set to a value. Then I do the focus command with this new connection:
rez_CGError = CGSOrderWindow(ownerCid, MY_TARGET_CGWINDOW_ID_of_other_app, kCGSOrderAbove, 0);
However this gives rez_CGError of 268435459, which I suspect means "current app does not have permission to use this ConnectionId (cid)". (Same happens if I call activateWithOptions first.
My Sources for the Private Functions
Here is the sources for some private functions I found - https://code.google.com/p/undocumented-goodness/source/browse/trunk/CoreGraphics/CGSPrivate.h
This one source here contains a function that is not in the above link - CGSGetConnectionIDForPSN - i test it and it exists - from - https://github.com/mnutt/libqxt/blob/767498816dfa1742a6f3aee787281745afec11b8/src/gui/qxtwindowsystem_mac.h#L80
I have created an app that creates a grid dynamically, as well as lets the user make changes to one of the grid columns via a 'numberfield' editor. Everything is working great in the debug environment but when I try to edit one of the fields in the Rally environment it crashes the app. From the looks of it, the iframe containing the app is just reloading altogether.
Now, here's the weird part that may be a clue to what's going on. The app crashes after I click elsewhere on the app (committing the change) but if I scroll the mouse wheel somewhere on the app, the spinner loses focus (no up/down arrows) and then if I click somewhere the edits are applied and the app doesn't crash. Once again in the debug mode I don't need to go through this, I can just click elsewhere and the changes are applied.
This is a known issue with 2.0p5 that will be fixed with the next release of the SDK. Basically it's using a sledgehammer to respond to the fact that something was edited and refreshing it. Since the new SDK can communicate with the message bus this is totally unnecessary...
In the meantime you should be able to patch your app by defining a global Rally.getApp function that returns your app instance to prevent the hard refresh:
//In your app definition give it an xtype:
Ext.define('My.App', {
extend: 'Rally.app.App',
//...
alias: 'widget.myapp'
//...
});
//Find the app instance by its xtype and return it
Rally.getApp = function() {
return Ext.ComponentQuery.query('myapp')[0];
};
You can then delete that code once 2.0p6 is released and you upgrade.
I'm developing a cross-platform browser extension, and have based all my code on the Chrome-way of doing this. I have counted on that the background page will be accessible from the options page, which in Safari extensions turns out to be not possible (since there is no such thing as an options-page). You can only access safari.extension.globalPage.contentWindow from within the extension popup, and the background page itself.
Now, I have an options page, which is an html-page within the extension bundle, and so far I haven't found a way for Safari to give it extension "rights". The closest I have come is adding a content script that's only added on the options page. This seems a bit silly, since the html page itself is in the extension bundle?!
Others have suggested using asynchronous ping-pong style message event handlers, and even the canLoad-mechanism (which is "only" able to run in a beforeload-event). I have been able to hack the canLoad-mechanism for synchronous messaging by forging the BeforeLoadEvent:
// Content script (run from anywhere)
var result = safari.self.tab.canLoad(new BeforeLoadEvent, "data")
-> "return value"
// Background page
safari.application.addEventListener('message', function(e) {
if ( e.name === "canLoad" )
e.message = "return value";
}, true);
It's a hack, but it works. However, I am crippled by the message transport serialization, since I need to be able access methods and data on my objects from the background page. Is there anyway around this?
Possible ways that might work but I don't know if possible:
Access options-page window-object from backgrounds page. Is that possible?
Message passing, need to bypass message serialization
Any shared/global object that I can attach objects to and fetch from the options page?
Make Safari run the options.html page from outside the content-script sandbox? It works in Chrome since they are both within the extension-bundle. It's quite annoying that safari doesn't do this too.
Run the options-page from within the popup. This is promising, but it crashes safari (which is very promising!). However, from the looks of it it's just something to do with a CSS animation in my options.html page. The biggest issue is that it has to be able to open an OAuth2 popup, but thanks to being able to programmatically open the popover, it might be a non-issue. However, this option is the most realistic, but I would rather have it open in a new tab.
Any suggestions and hackish workarounds would really help.
I'm using JavaFX 2. I want my frame to open maximized but I'm not seeing a way. I searched a bit on the internet without success. For the stage I see setFullScreen() and setIconified() but I don't see anything like setMaximized().
The Java 8 implementation of the Stage class provides a maximized property, which can be set as follows:
primaryStage.setMaximized(true);
When evaluating the sourcecode of the Ensemble.jar provided with the samples of JavaFX 2.0 SDK, the currently valid way to achieve window maximizing is
Screen screen = Screen.getPrimary();
Rectangle2D bounds = screen.getVisualBounds();
primaryStage.setX(bounds.getMinX());
primaryStage.setY(bounds.getMinY());
primaryStage.setWidth(bounds.getWidth());
primaryStage.setHeight(bounds.getHeight());
(you find similar code in WindowButtons.java)
The 'maximize' button is still enabled and when clicking it, the windows will grow a bit more (Windows OS). After this the 'maximize 'button is disabled. In the provided example the standard buttons are replaced. Maybe this is still an issue.
Better use Multi-Screen compatible maximize logic:
// Get current screen of the stage
ObservableList<Screen> screens = Screen.getScreensForRectangle(new Rectangle2D(stage.getX(), stage.getY(), stage.getWidth(), stage.getHeight()));
// Change stage properties
Rectangle2D bounds = screens.get(0).getVisualBounds();
stage.setX(bounds.getMinX());
stage.setY(bounds.getMinY());
stage.setWidth(bounds.getWidth());
stage.setHeight(bounds.getHeight());
try this simpler code
primaryStage.setMaximized(true);
and it fills up the whole screen
. note that if you remove maximize/minise buttons the application will fill the whole screen as well as remove the taskbar so mnd your initStyles if you have any
Use this to remove the Minimise, Maximise Buttons :
primaryStage.initStyle(StageStyle.UTILITY);
Where primaryStage is your Stage object.
