neumorphism | Neumorphic UI designed one pager Website template | User Interface library

It appears to me that this is based on a perspective issue (zoomed vs regular). Looking at the two images you provided, the button with 'D' text does not alter its perspective. Maybe this is due to the ambient area between the edge of the text area and edge the button. Have you tried changing the background of the button and text items separately?

Add a change event listener to the power button, then check whether it is checked with the checked property:

Try using ConstraintLayout for this purpose. It works well for me. Just change your layout to ConstraintLayout and set all the constraints according to your needs. Hope this works.

Fixed the select css, working example:

The background image's position and size was not set correctly.

The changes include:

• Setting the background-position, background-size, and background-repeat properties of select, and removing arbitrary CSS properties from the same selector.

Try to remove the ViewTreeObserver.OnScrollChangedListener when the fragment is destroyed this will avoid any listener that can be attached to a destroyed fragment context not to be triggered whenever you leave and come back to this fragment.

First: make a global field for the listener

to remove black border from button just add broder-style:none to button. Added one more button with hover and active styling.

for creating Neumorphism effect you can check https://neumorphism.io/

Try this

Setting corner radius half of height and width and setting padding to 0 .

The solution is to create a custom subclass of QGraphicsEffect and using gradients.

At first I thought about following the same concept used for CSS, subclassing QGraphicsDropShadowEffect and using another one internally to draw the "other" shadow, but I didn't like the result: in certain situations (usually when radius and contrast are too big) it just doesn't work:

If you look closely, you'll find out that the result is too similar to the drop shadow, like the object is floating, while it should be "extruding".

The only effective solution I found was to manually draw everything, using linear gradients for borders and composite gradients for the corners. While the first is pretty logical, the second required a bit of ingenuity by using composite modes of QPainter: Qt only has radials and conical gradients, but there is no "mix" between them.

The trick then was to create a radial gradient for the "light" color with the full color at the center and the same color at the border with 0 alpha, then superimpose a conical gradient for the "dark" color (with the "dark" color on start and the "light" at 90°), which will be painted using the alpha component of the first gradient.

Then it's just a matter of creating functions to update each one of the properties: distance (the extent of the effect), color (used for the gradients, defaults to the application's QPalette.Window color role), origin (the corner used as the "source" for the light) and an optional clipRadius for rounded borders.

Some important notes:

• since it's a QGraphicsEffect, it can only be applied to a "parent" widget: children cannot have another effect applied on them, which means that if you have a container like QGroupBox or QTabWidget, you have to choose if you want to apply it to the parent or to each of the children;
• due to its "simple" nature, it only supports rectangular shapes: if a widget has a mask, the effect shape will still be based on a rectangle;
• layout margins and spacings should be taken into account, as multiple effects could overlap if the widgets that use them are too narrow; I'd suggest using a QProxyStyle and set a minimum default for both PM_Layout[*]Margin and PM_Layout[*]Spacing, and return a value according to the length property;
• the clipRadius property allows rounded border clipping, but it's not perfect, since QPainter's clipping doesn't support antialiasing; I'll see if I can address this issue in the future;
• when applied to QGraphicsScene items, similarly to QGraphicsDropShadowEffect, the effect is in device coordinates, so transformations (rotation, scale, shearing) won't be applied; I'll update this answer whenever I'll be able to solve this issue too;

And here is a comparison between the Qt QGraphicsDropShadowEffect, the css emulation, and my NeumorphismEffect (the last two have rounded borders: the css version uses the border-radius property while mine is set with clipRadius):

This is what I did to create an inner shadow like the one in the picture. I created it in another swiftui file and just called in in my main content view but you can display it however you'd like.

I created a Button in a ZStack only because I first recreated it with a rounded rectangle but I think this would would in a HStack or VStack as well just haven't tried them. To create the inner shadow I created an overlay and clipped the shadows to the shape.
