Frameless | The spiritual successor to Less Framework

There are many question on StackOverflow about detecting whether an iPhone device has a notch in the screen, such as this one. The answers almost always recommend using the safeAreaInsets property of the top window. I have used that in my app to determine whether a status bar should be shown, from the prefersStatusBarHidden method of the currently shown view controller. I would like to show the status bar when there is a notch, but not when not. It works fine in all my tests, but for some customers the status bar disappears sometimes, even though they use a device with a notch (an iPhone 12 Pro Max).

I looked into it, and I think the problem is probably caused by a recursive call to safeAreaInsets, see following call-stack:

It makes some sense. In order to determine how large the safe area needs to be, iOS needs to know whether the status bar needs to be shown. And therefore, it calls prefersStatusBarHidden of the visible view controller, which then uses the safe area to determine that....

Despite the recursive call, it still works for me in tests, but as said, it fails sometimes for some users. I need to work with prefersStatusBarHidden, because at top-level the app consists of a UITabBarController, for which only one tab hides the status bar. The other tabs should always show the status bar, independent of whether there is notch or not.

I have considered checking the device type with sysctlbyname with "hw.machine" argument, and then use a mapping table to get the notch/no-notch result. But that has the disadvantage that the mapping table would need to be updated for each new iPhone model, and that it doesn't work on the simulator, which always returns the Mac machine name.

Any ideas how to solve that in a better way? I could simply avoid the recursive call, but will that solve the problem?

My code that determines the notch right now (Objective-C):

I am new to PyQt5 and am having a hard time figuring out how will I convert the code accordingly so that it is frameless. I have used flags but it keeps giving me an error that the "UI_MainWindow object has no attribute 'SetWindowFlags'. The problem is in the execution part but I'm unable to figure out how to make the alterations.

I'm trying to create a custom TitleBar. What I've done is create a frameless window, then use static control for my custom TitleBar.

I've finished setting it up, the only missing function is the drag event.

So I am trying to create a window (QDialog) with a width of a 100% (of the screen) and a height of a fixed value, eg. 60px.

I tried to achieve this by setting the maximumSize's height property to 60px, leaving the width to whatever it was. (16777215) I also set the horizontal sizePolicy to Maximum, and the vertical to Fixed, with stretch values of 1 and 0 respectively.

As you can see in the picture above, the dialog appears centered, but not stretched at all horizontally.

The code is pretty simple as seen below, its just a frameless QDialog:

So i have this project with Frameless windows and in order to move them around the screen made such functions for every window:

window.h

Running into a really strange quirk and can't figure out what I'm doing wrong:

init.js

For my frameless qml app i made close, minimise and maximize icons in ms paint (28×28 pixel art) and then added transparent background with photoshop.

I put them as icons on qml buttons. But they are looking blurry.

I tried disabling antialiasing, mipmaps, smoothing but still blurry.

Any help ? I want them to look pixely like minecraft text.

Edit : I appears that qml uses linear scaling for images. But for pixely look i need "nearest neighbour" scaling.

How can i use nearest neighbour in qml ?

I'm following this article to set up Electron and Svelte.

I wanted to make my window frameless so I enabled frame: false in index.js and it is successfully working and there is no title bar.

According to this StackOverflow answer, to enable moving, I need to use:

I have been trying to figure this out for the last two days. I want to make my window frameless, I saw in a couple of resources that I should be using Qt.FramelessWindowHint . However, it doesn't want to work and I can't figure out why.

Can someone please point out what's wrong with my code, as I am very new to PyQt5? (I have commented out sections that are related to some other files)
