QUESTION
Reported to Qt as a bug: https://bugreports.qt.io/browse/QTBUG-93475
I am re-drawing a QPixmap
multiple times in different locations, with differnt rotations by transforming the QPainter. In certain situations the QPixmap
is not drawing correctly. The GIF below shows my initial discovery of this issue with a QPixmap
containing a green cylinder, notice how the rendering behaves as expected to the left of the GIF, but there is a boundary beyond which the rendering is incorrect. The QPixmap
content appears to stick in place, and the pixels at the edge appear to smear out accross the rest of the pixmap. In the GIF there is a magenta background to the QPixmap
, this because the targetRect
used by QPainter::drawPixmap()
is also beuing used to seperately fill a rectangle underneath the pixmap, this was because I wanted to check that the target rect was being computed correctly.
To keep things simple I am simply filling the QPixmap
with magenta pixels, with a 1 pixel wide transparent edge so that the smearing causes the pixmaps to dissapear completely. It doesn't show the image "sticking" in place but it clearly shows the boundary as beyond it the pixmaps seem to dissapear.
I have been experimenting with this myself and I believe this to be entirely caused by the rotating of the QPainter
.
The angle of rotation seems to have an effect, if all of the pixmaps are rotated to the same angle then the boundary changes from a fuzzy diagonal line (where fuzzy means the boundary for dissapearing is different for each pixmap) to a sharp 90 degree corner (where sharp means that the boundary for dissapearing is the same for all pixmaps).
The range of different angles also seems to play a part, if the randomly generated angles are in a small 10 degree range, then the boundary is just a slightly fuzzier right angle, with a bevelled corner. There seems to be a progression from sharp right angle to fuzzy diagonal line as the number of different rotations is applied.

...ANSWER
Answered 2021-May-06 at 14:43This issue is very interesting. As far as I could test, your code looks good, I feel like this is a Qt bug, and I think you need to report it to Qt: https://bugreports.qt.io/. You should post a single piece of code to illustrate the issue, your second one from your "Update" edit is good: it makes it easy to reproduce the issu. Maybe you should also post a small video to illustrate how things are getting wrong when you zoom in/out or move the area with the mouse.
I tried some alternatives to hopefully find a workaround, but I found none:
- Tried to use a
QImage
rather than aQPixmap
, same issue - Tried to load the pixmap from a frozen png/qrc file, same issue
- Tried to use
QTransform
to play with scale/translation/rotation, same issue - Tried Linux and Windows 10: same issue observed
Note that:
- If you don't rotate (comment
paint.rotate(entity.rotation_);
), the issue is not visible - If your pixmap is a simple mono-colored square (simply fill your pixmap with a single color using
pixmap_.fill(QColor::fromRgba(0x12345600));
), the issue is not visible anymore. That's the most surprising, looks like a pixel from the image is being reused as background and messes things up but if all the image pixels are the same it does not lead to any display issue.
Workaround proposed by the Qt team
"The issue can easily be worked around by enabling the SmoothPixmapTransform render hint on the painter"
QUESTION
I am new to flutter. I am adding a toggle switch. Toggle switch is resetting each time after selecting the dropdown I used below the toggle switch. I have not used any model for the switch. But I am not sure why the toggle switch is resetting.
...ANSWER
Answered 2021-Apr-28 at 12:06The package you are using has an argument called initialLabelIndex. There, you can set where the switch "lays" on, every time it initializes.
Create an integer for storing the labelIndex before your build function:
QUESTION
I am working on a project using where I want to achieve a layout like the one in the picture. This is what I have done so far. I am able to align the sidebar to the left and the header to the top (behind the sidebar). However I have problems aligning the contentContainer aside the sidebar and just below the topper. I was thinking of aligning the container and sidebar aside each other by width: 20% and width: 80% but the sidebar must have a fixed width size because I don't want the width to change when the app gets resized.
I also have problems within the contentContainer. I have made it a flex-box with column direction. Trying to place the headContent on flex-start, mainContent on center and footerContent on flex-end. Yet it just doesn't work. For your information, it is a reactjs app, if it is of any importance. Here is the code I have tried.
...ANSWER
Answered 2021-Apr-20 at 12:09As I can see, you have already done almost what you wanted. Except for an unclosed tag, it was all fine. The only problem is the classes. You used a
className
attribute instead of a class
attribute. That is the main problem. If it isn't, see the picture below and tell me what else you need:
As you can see in the comments, we had a conversation and I have fixed it. So, now you need first of all to change the className
to class
and then you need to change your CSS file to this:
QUESTION
I have a project where I need to create a certain type of card. These cards contain a gradient background when hovered over. I have added a before item that is shown when the item is hovered over. In order to contain the background gradient within the card I have added a clip path attribute to the card.
But the problem I am facing is that the clip path doesn't clip the rounded border border-radius: 0.5rem;
. I have searched and found that it is possible by using a polygon to clip path.
I have found a link where you can generate poly items to clip to: Clip poly generator.
But i cannot find a perfect polygon that fits. The circle is to rounded and the bevel item only has sharp borders.

QUESTION
I have the following SVG to render checkers on a board where both the board and checkers have a nice bevelled effect. I'm very happy with the effect on Chrome (and Safari) but Firefox seems to ignore the effect.
Would appreciate help understanding why it doesn't work as all the primitives show as supported in Firefox (caniuse.com).
...ANSWER
Answered 2021-Jan-20 at 15:58Firefox is not ignoring the effect, it's just very faint. If you increase surfaceScale and bring the point light nearer to the drawing surface, you'll be able to see it more clearly.
There are a lot of inconsistencies in lightsource implementations cross-browser - for example FireFox uses sRGB color space by default for lightsources, so you have to set Chrome to use it explicitly. Then, you need to tweak things until you have something that looks the same. For example, specularConstant doesn't seem to be doing the same thing in each browser at 0.3 - but setting it to "1" seems to be consistent. Here is a filter that looks mostly the same. I had to switch out the fePointLight for a feDistantLight to avoid positioning calculation inconsistencies.
