Hello Dear @SGaist, Thank you for your message,
You are an active, I did read some good reply befor in this case from you in this froum...I know about
canOpenURLmethod, But i don't know how to call and use it....How we can use it? Thank you so much
Also:
- https://forum.qt.io/topic/46793/solved-using-objective-c-class-in-qt-c
- https://philjordan.eu/article/mixing-objective-c-c++-and-objective-c++
Can you show me one example in this case? It's not clear for me.
-
In your case, it's not as complicated as the link you found.
Change the file extension of your cpp class implementation to .mm and in the function you want to make the check call, something like:
NSURL *url = myUrl.toNSUrl(); bool canOpen = [[NSApplication shared] canOpenUrl: url];[edit: fixed class name typo]

It's NSURL

Start by reading https://doc.qt.io/qt-5/qurl.html#toNSURL, where you will see it's speltNSURL. -

Did you re-run qmake after modifying your .pro file ?
If not then either nuke the build folder and restart a build or force a run of qmake.
On a side note, your .pro file has two issues: you have
HandleURL.mmin both SOURCES and OBJECTIVE_SOURCES. If you are using a recent version of Qt, you don't need the later.The other issue is the backslash after main.cpp.

Can you help and guide me?
Thank you -
Are you building for macOS or iOS ?
I built successfully for macOS but you seem to target the simulator.
-
From the documentation, NSUserNotification is a macOS API that is not deprecated.
-
In your case, it's not as complicated as the link you found.
Change the file extension of your cpp class implementation to .mm and in the function you want to make the check call, something like:
NSURL *url = myUrl.toNSUrl(); bool canOpen = [[NSApplication shared] canOpenUrl: url];[edit: fixed class name typo]

How we can access to UIApplication? and how can call canopenurl?
Target is iOS using Qt.
https://developer.apple.com/documentation/uikit/uiapplication/1622952-canopenurl
-
It's written on the page you are linking as well as the URL: use the UIKit framework.

I don't know how to use UIKit, UIApplication in my Qt project.
I cannot find any solution and sample code for this.
Can you help me? -
The exact same as you did with NSApplication, just use UIApplication in place.

Also how we can access to
sharedobject when we are in another file?It's a globally object in
OBJECT C(.mm) files? -
The same way you did there. The function returns the singleton app instance.
