I am new to QT GUI programming, i am stuck with a scenario where I have to display the list (files) of a directory which has been saved on a particular date.
So, whenever a user click on a particular date on the calendar widget, I need to display the content of the directory.
How can I get the event when a user click on the calendar, and how can display the content of the directory?
Any help will be appreciated
Thanks...
Connect the QCalendarWidget's clicked() signal to a function/method. It provides a QDate depresentation of the day the user selected.
Here is a full example

My question is very complex, and my English is not that well, so please excuse if you don't understand me.
I have a SwiftUI File, which builds for each Item in a folder on my firebase an special Button.
If I touch this Button, it will hide. The problem is, I want that if the SwiftUI File reloads, I want to see only these Buttons which I haven't tapped before. (I want to Store which Buttons are Tapped). The Problem is, each time I reload the SwiftUI File, It'll make new Buttons, which aren't tapped yet.
My Question is now, how can I create only for the new Items in my Folder (on the firebase) an Button. The old once should be displayed too, if they were not tapped.
You can store Bool in Firebase. Just load items which false and when you tap a button you make the value true.
I used buddypress event manager plugin.
To display the event i should use this short code[activity-stream per_page=10 ].
Now 10 events are displayed correctly. But image will not displayed. If i create an new event means the Name of the event, Who's created , Time will be displayed.
But i want to display image also. Kindly help me to fix this.
Thanks
I would like to create an app in Android Studio that has a Button in Main Activity and when i clicks this button, it should open a google map with my customized lat,lng markers and camera functions as an another activity. I tried this one by creating a Button in the Main Activity.XML and wrote buttonOnClickListener() by specifying Intent that MainActivity.this,Mapfragment.class.For this I selected GoogleMaps as my start Activity instead of blank activity at starting of my project. And also for this MapFragment, I got Google maps API key. But when I run this App on my android mobile, it simply opening google map with my customized lat,lng instead of showing my Main Activity which is having a Button in it. I am confused with this, can anyone help me out of this problem.Thank You
Yes, I got it. I tried to solve this problem and got a solution for it. Initially as I said, at the starting of my project I selected a google map activity instead of blank activity. So now, to get a Button in my Main activity, I have created a MainActivity.XML in Layout folder and added a Button to it. Then, for this MainActivity.XML file corresponding .Java class was created and specified the MainActivity.XML in it and declared the Button and wrote OnClickListener for Button, so that when the Button clicks it should open my google map fragment with customized location. Importantly, we should specify this mainactivity.java in the Manifest.XML as an Activity specifying it as a Launcher activity in the Application. Now, run the app and first it displays MainActivity with a Button and now when I clicks it, it opens my google map fragment activity with the help of Intent.
Suppose I've a Qt app based on QWidget, in which I'd like to obtain a "feedback" everytime I press a QPushButton, I rotate a QDial, I press a mouse button. My question is: how can I set a slot that informs me everytime something happened inside my app built for a touchscreen, in which I need to know when user does something on it.
MousePressEvent partially solves my problem; so when user touches the screen, MousePressEvent warns me about it. Problem is related to widgets as QPushButtons or QDials.
At the moment, I've already arranged my widgets with a lot of subwidgets; number of pushbutton is about 300. How can obtain triggering signal when one of them is pressed without re-edit every single button?
You can use an "event filter" that is installed on QApplication instance. This filter will receive all the events in your application, afterwards you can check event type and object type to pick the events you are interested in. See my answer to another question here for details.
QApplication.postEvent(object, press)
I want to simulate the keypress and mousepress in the select file dialog, which is popped up by clicking file input in the QWebView. I don't know what the object is. Any ideas on how to obtain it?
Make a stock QFileDialog in another project, and dump its Object Tree.
