A part of my form contains QGroupBox (Status Box) with 4 child QGroupBoxes arranged in a grid layout (2x2). Two bottom QGroupBoxes (Widget 1 Box and Widget 2 Box) contain widgets of fixed size (with set minimumSize and maximumSize) so they're non-resizable at all in both directions. Because of that rigid size constraints top row of QGroupBoxes (Summary Box and Helper Box) can only be resized in vertical direction.

And here comes the troublesome part. Top-left QGroupBox (Summary Box) have grid layout 5x3 while top-right (Helper Box) have vertical layout with 6 rows. If I have naive widget placement as shown on picture 1 Qt is enlarging vertical size of both labels in top row to make height of both QGroupBoxes equal (see red arrows on picture 1).

This is definitely that I don't want so I've added vertical spacer to the bottom of Summary Box and from the first glance it worked (picture 2). But only from the first glance... What you see is the minimum height of my whole form and the bottom side of spacer and last QCheckBox in the Helper Box seems to be aligned.

If I'm expanding my form vertically this spacer grows a bit and that causes the increase of height of both top QGroupBoxes. As a result spacing between QCheckBoxes increases too and we can also see that top and bottom spacing are unequal for the top-right box (see red arrows on picture 3).

I've tried to play with sizeType for my vertical spacer. If I set it to Minimum or MinimumExpanding then the spacer doesn't grow on resize (and doesn't shrink, too) but it appears to be expanded to the size as on picture 3 (corrupting spacings between QCheckBoxes too). If I set it to Maximum, Preferred or Expanding then I observe the same behavior as described above for picture 3.

What is the proper way to achieve alignment for two QGroupBoxes in a row of grid without affecting spacing between elements (e. g. in that case make vertical spacer to fit only single row of grid layout and never expand/shrink)?

I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:

• In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.

• For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.

Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?

I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".

Below you find a MWE consisting of a widget mwe_qt_widget.MyWidget with a combobox, a pushbutton and a label that gets updated by the other two subwidgets:

My problem is that, I have a List of Icons(CustomWidgets) what are provide by an API. I need put this icons in my App but when the are 7 or more its looks like these:

I want to put the icons in separate rows. I've tried out a method which split the list in 2 and add it dynamically but didn't print anything because I'm using a FutureBuilder to print the Icons.

Here is the code:

I have having 3 error about the object cant be assigned to parameter including int, string and double . I'm trying to fetch data to create a chart-bar to display and process the data.it fetches from another widget called Transaction.

I am trying to stylize my form using bootstrap. As you know bootstrap uses a lot of classes in order to do what it does. By googling I have found to inject some new classes into my form I could use widgets with django. My form is as follows:

I am trying to understand how JavaRx's Flux.merge and switchIfEmpty work together in regards to the below code as I am a bit confused on results I am seeing which is no doubt the result of my not fully grasping Java RX.

My question is ... If the call to wOneRepository... returns an empty list or the call to wTwoRepository... returns an empty list, will the switchIfEmpty code get executed? Or will it only get executed if both calls return an empty list?

In PageViewBuilder, instead of swipe gesture I want to move to the next page using onTap on an ArgonTimerButton which I found on pub.dev. I created a controller and used controller.nextPage() but it gives me this error:

I am trying to add api response data into datatable row.

My api response is look like this

Now: My goal:

I am using the syncfusion_flutter_charts package to display the chart and that table view is so annoying. How to remove that? or how to do this kind of chart using custom widgets?
