QUESTION
How to get the return value? Attach my code. My intention: Want to check the QListWidget and if it's empty, a message Box popup will raise and ask the option from the user. Problem: At the stage of beginning itself, a Message box popup will display, (I don't want it at the beginning stage), If the QListwidget is empty then the MessageBox popup will display as desired, and if we select "Yes" or " No" Button, Nothing will return/print in the first file. How to resolve?

Answered 2021-Jun-15 at 16:49In first it is not necessary to make the verification be done in a new class, it is also logical that you invoke func_create_newitem since as you point out that method must be invoked when the item was not found.
QUESTION
I am developing a Master-Detail App.
I have 1 EntityType for Master View (Master) and another EntityType for Detail (Detail). I have created an Association from Master to Detail.
Master View works perfectly. Detail has 2 parts:
- Header: which shows a few fields from the Line selected in Master view. (Name, ID and not much more)
- Body: it has 2 fragments. These 2 fragments displays the info from Detail Entity.
My Issue is:
- I got errors in the Console cause fields loaded on Fragments are searched from the Entity type Master. It means that the View && Fragments are loaded before the second Binding is done.
What I have tried:
I used the BusyIndicator and controlling the events (
attachRequestCompleteand/orattachEventOnce("dataReceived")) from the Model in theonInit()assigningview.setBusy(false)when they are reached. It doesn't work for me.I tried it out but when the Event of the 2nd binding is reached the view is already loaded.
After loading the info in Master View:
...ANSWER
Answered 2021-Jun-14 at 07:56It looks like your code binds relative the path "Master2Detail" on the detail side. BUT initially there should not be any existing binding in any parent view.
Your app should look more or less like this for binding path. UI5 is moving up the element to find data:
App-> Flexible ColumnLayout/SPlitView -> Master
App-> Flexible ColumnLayout/SPlitView -> Details
So adjust your bindings a described here OData error when bind to an element in a Master-Detail app
Second, you get this error because initially there is no relative binding in between your master bound element and the detail. Therefore, UI5 can only think this must be part of the master.
If you make up a relative binding in-between, you must inject the fragment by yourself. E.g. load the fragment, bind the loaded control(in aour case the VBox) and then use addItem etc. do attache it to the view.
QUESTION
I'm trying to access to a variable in a multiprocessing worker within a QThread.
I made a minimal example to highlight my point:
...ANSWER
Answered 2021-Jun-11 at 10:50Child processes in Python do not share memory by default—code running in one process cannot access or change the memory used by another process. This means that each process has its own copy of each of the variables you are using, including the mp_worker_class.nbiter variable. Hence, you don't see changes that a child process makes to its mp_worker_class.nbiter variable from the parent process (or any of the other child processes, for that matter.)
As you have seen, we can get data from a parent process to a child process by using the args keyword argument to the multiprocessing.Process constructor. However, this simply copies the data from the parent to the child; we're still not sharing memory between the two processes.

How to update the selected item in the proper QLineEdit? 3 textboxes and filled by various sets of data. If I click some items in QListWidget, every time first QLineedit only updated. Instead of this, I want to update data to the corresponding QLineEdits. ( for Ex: if textbox1 is focused, then the selected item will update in textbox1. If textbox2 is focused, then the selected item will update in textbox2). But In My case, Every time textbox1 is only updated.

Answered 2021-Jun-09 at 16:51You are passing the same instance of same listbox again and agian to MyFile constructor, and connecting the listBox clicked signal again and again, but connecting the signal works for the first time only, so you need to disconnect if it is already connected, so first try to disconnect the signal if it is connected:

It's my code. How to store the lastly clicked/checked button as default in the next opening of the programme? For example: If we run the programme and click the 3rd button and close the entire programme. Whenever I reopen/re-run the programme, the lastly clicked button is checked by default ( ie. third button is checked by default)
...ANSWER
Answered 2021-Jun-07 at 14:59You can use QSettings to save and restore data. Note that values are serialized as QVariants, so you cannot, for instance, save a custom python subclass instance.
In order to properly use QSettings you must set both the Qt application name and organization name (otherwise data won't be stored anywhere).
It is possible to save settings in other ways, but for general usage it's better to use the default behavior.
Note that, since values are stored as strings, Qt can only try to guess the actual type, so it's always better to specify the type when using value() (see the case below).
Then, while by default Qt is able to automatically group radio buttons and make them exclusive (see the autoExclusive property of QAbstractButton, which is set to True for QRadioButtons), for this kind of situations it's better to rely on a QButtonGroup, which not only allows better control on the buttons, but also allows identifying buttons member of the group by using unique IDs they were assigned to.
Finally, it's just a matter of connecting the appropriate signal of the button group to the function that saves the currently checked button.

Want to create a custom widget with QListWidget, Qlabels and QCombo box.
In my code, contains one QListwidget,
three labels to display the number of items in QListWidget, First one for total available items in QListWidget, the second one is on filter condition (item starts) and the third one is also to display the number of items for the filter(Match Contains).
And one combo box for setting the QListWidget default view. How to make it.

I am trying to get two different choice box to work at the same time However I am getting a nullpointer error in the initialize method. which is kind of weird cuz I am trying to initialize what is in the choice box but the IDE is giving me a nullpointer exception.
this is my code
...ANSWER
Answered 2021-Jun-06 at 08:01The issue is that you never say new ChoiceBox, so when you reference them with inputPieceType.getItems().addAll(pieces); or inputPieceAllience.getItems().addAll(allience); on line 62 they are calling methods for an item that was never created.
You could do something like this to initialize the objects:
QUESTION
I using extjs version 7.4.
The icon is clearly visible in the example of Sencha. https://examples.sencha.com/extjs/7.4.0/examples/kitchensink/#menu-buttons
However, icon isn't displayed in my actual code screenshot
Is there a problem with my source? Or is it a Sencha bug?

...ANSWER
Answered 2021-Jun-02 at 18:39I guess you missed to define the classes like here:
As an alternative you can try to set the icon like that:
- iconCls:'x-fa fa-home'
Which prefix you will need depends on your FontAwesome version.
Following this approach you might need additional classes to scale the icon. But i am not sure.
