QUESTION
I have made a GUI application using PyQt5 module for my Unit converter for Time(Meaning converts the units of Time like seconds to milliseconds, minutes to milliseconds, etc) using a QtDesigner. But the only problem I am facing is that I do not know where and how to input the function of my application to make it work as a unit converter for Time. Below is the full code of my GUI application:
...ANSWER
Answered 2021-Jun-12 at 03:00Qt uses a concept called "Signal/Slot mechanism".
Every Qt object (QObject, which is inherited by all Qt widgets) is able to "emit" signals with a (possibly empty) amount of arguments, and that signal can be "registered" to slots, which are functions that will be called everytime that signal are emitted.[1]
A typical case is a button (normally, a QPushButton), which has a clicked
signal[2] that is emitted whenever the button is clicked, meaning that the mouse cursor is over the button both when the mouse button is pressed and then released.
Every Qt widget has different signals depending on its purpose.
For instance, the QLineEdit control has a textChanged
(that is emitted whenever the text is changed, even programmatically) and textEdited
(which is only emitted when the user actually types something in it).
A QComboBox has the currentIndexChanged
signal, emitted whenever the current item is changed (for instance, opening the popup and selecting a different item, or by using the mouse wheel over it).
In the following code, I'll be connecting to "slots" (in this case, simple python functions) by completely ignoring the arguments of the related signals, but there are cases for which those arguments are actually needed.
The idea is that whenever the user types something in any of the line edit fields, the related function tries to convert the typed value to a numeric one, and then, based on the current content of the comboboxes will do the proper conversion.
Consider that:
- QLineEdit is not a suggested control for numeric input. A QSpinBox (for integers, otherwise a QDoubleSpinBox for floating points) is more suited for such situations; alternatively, setting a QIntValidator or QDoubleValidator on the line edit is possible.
- Using
combobox.addItem()
allows setting user data for each item along with the visible label; I'm using that "hidden" data by means ofcurrentData()
for multiplicators that are used for the conversion; this also means that you should remove any existing item for those comboboxes from the UI in Designer. - Editing files generated by
pyuic
is considered bad practice (for a lot of reasons); I strongly suggest you to carefully read the official guidelines about using Designer, generate again the files from the UI and never touch them again (unless by overwriting with pyuic): those files should always be used as imports only. In the following code I'm assuming you've updated your UI (by removing the items in the first two combos) and converted them again to a file namedunitConverterUi.py
, which will NOT be the actual script you'll be running. - Using fixed geometries (manually positioning and resizing widgets) is rarely a good idea. Remember that what you see on your screen is almost always never what others will see on theirs. Read more about layout managers and how to use them in Designer. User interfaces should be able to adapt to the screen and system settings of the user (what is called "responsive design" in modern website design).
QUESTION
below I have posted the code for my drop-down menu. At the very end, there is a variable called variableToChange=""
.
Probably it is an easy question for the more experienced ones but I want every time I press some button to change the value of the variable. Let's say it should take the text of the button as a new value.
I guess it should be implemented somewhere into the on click
part but I lack the experience here so I can't really implement it. I would really appreciate some help.
Update: Expected scenario would be: when I press the button called AA the value of variableToChange should be changed to "AA". Similarly, if I press afterwards BC it should be changed again to "BC".

I have taken over the code from this post. As I have explained there, I have basically no HTML knowledge, yet I have this HTML part of my project that I have to finish.

QUESTION
I use lots of boxes to display information, and their current style is this:
...ANSWER
Answered 2021-Jun-04 at 17:21If I understand correctly, you don't want the .box
flex container to occupy 100% of the available width like its currently doing. One way to ensure the width of .box
adapts to the content of the element is using width: fit-content
.
Note:
fit-content
isn't supported in Internet Explorer, so using the method below which doesn't use fit-content would ensure better support.
To make sure the content is centered vertically and horizontally on the page. You could make the body
(or another parent container) a flexbox and specify min-height: 100vh
so the content fills at minimum 100% of the viewport height along with align-items: center
to vertically align the child .box
container along the cross-axis in the center of the page. To ensure that .box
is centered horizontally along the main-axis, you can use justify-content: center
or margin: 0 auto
to take advantage of auto margins.
QUESTION
I have been stuck in this for whole day. I am creating a UI using PowerShell forms. In that:
- user select an option from 1st combobox. click button Go
- Based on the selection, a panel will appear having another combobox.
- if user select another option in 1st combobox then another panel appears with another combobox
- After selecting options from panel comboboxes, user clicks on start button.
- This leads to a function which stores the selected options to a variable.
Problem
- Now when user selects the options from the comboboxes of panels, I am using $combobox.selecteditem.Tostring to get the values. But it gives me NULL result. Here is my code.. ...
ANSWER
Answered 2021-Jun-03 at 18:03The issue is that your variables are being set in a function, so they are scoped to that function. There's really no reason to put that in a function, put it directly in the .add_click()
instead. Or if you feel that you need to keep it in the function you can scope the variable like you did with $global:ButtonClicked
and set them to $global:Link
and $global:LinkType
.
Edit: Order does make a difference in PowerShell, so I did move some stuff around in your script to make it work right, but I was able to get values to reflect fine when I put them in the global scope.
