General and Desktop

Thanks for the reply. I was able to use this approach to solve the problem by storing the image and later compare the image stored.

Hello! I have the same problem, I'm not able to make the window blur the desktop. I've already seen the deepin implementation and I couldn't find where they apply this effect. Do I have to call a function from KWin(In my case), XCB, X11 or the QPainter is enough? I saw some implementations using the following code alongside a way to grab a screenshot of what is behind, but ,at the moment I make it, I can't reapply because the blurred image stays on top (keep blurring the same screenshot). QT_BEGIN_NAMESPACE Q_WIDGETS_EXPORT void qt_blurImage(QPainter *p, QImage &blurImage, qreal radius, bool quality, bool alphaOnly, int transposed = 0); QT_END_NAMESPACE

This helped. Did the command like the documentation said so and imported the file and bam! Very nice!

Hi, I currently don't know. However, one important thing is that Qt 5.3 is more than outdated. You should consider updating to more recent version.

@Qwerty123098 hi You can use "Topic tools" button to mark this topic as "Solved", also it would be better if you can use more meaningful titles for your posts

@huy-cong I am trying to load my mp4 video into qt assistant, but I just get the message "Your browser does not support HTML video. ". I am using Qt 5.13 and the html I am using to load the video is: <video width="400" controls> <source src="videos/mov_bbb.mp4" type="video/mp4"> <source src="videos/mov_bbb.ogg" type="video/ogg"> Your browser does not support HTML video. </video> Can you tell me how you embedded your video in your .html file? Thanks!

@Vildnex said in Qt5 - CPP - How to resize a QScrollList: I don't know about the answer you are seeking, but while you are waiting for someone else to answer: auto ratioW = 8; auto ratioH = 3; float thisAspectRatio = (float) event->size().width() / event->size().height(); if (thisAspectRatio < ratioW / ratioH) { That ratioW / ratioH looks like an integer division to me?

@Bonnie If I can chip in, now that OP seems happy. So, you managed to do it even with parameters without having to use std::function(). I thought I read that was needed when I looked at SO posts, but perhaps that was older version of C++. Armed with your answer, I just went back over code and did my lambda-to-be-used-many-times-in-one-function with your auto func1 = [](...) { return ...; }; and it wasn't so hard after all! So thanks very much for example.

cython is also an possibility to wrap c/c++ code in python and its easier to set up than swig.

That worked!!! Thank you!

@student I don't do "EDA" so I wouldn't know. If you state that "ore code should be Qt" etc., then presumably someone has already addressed the interface between TCL & Qt, else there would be a problem.

@Dariusz If you check the PySide documentation you will see that there is no overload taking a lambda or any function/method. There are only overloads accepting strings containing method name. So, it seems not possible with PySide. But instead of using QApplication instance you could create your own class with methods you want to call using invokeMethod.

@gde23 touch screen monitor working well. I tracked press/click events via qDebug()<<"test ";

I have no folder /usr/lib/librosco but in /usr/lib there are the three librosco.so ,librosco.so.2 and librosco.so.2.0.0

I build it by myself

@SGaist I'll pull something together. You will need blender 2.83+ however to test it.
