Mobile and Embedded

@wohehe said in How to make a widget recieve mouseevent?: @SGaist Hi , do you need the code? By the way, I face this issue on embeded system, when I use this code on PC, seems everything works well. A minimal compilable example would be good. Embedded device ? Which device ? Which OS ? Which QPA backend ?

So i manage to make a workaround. I just set the variable to empty in the file: qtbase/mkspecs/common/gcc-base.conf #QMAKE_CFLAGS_SHSTK = -mshstk QMAKE_CFLAGS_SHSTK =

my goal was to test performance of boot2qt vs raspbian, since I want my raspberry just for my app, it will boot and go straight to my app. Since boot2qt is a custom image to run Qt apps I thought it was my best option. Thanks for your time!

@Kyeiv , I think yes, because a lot time ago, a mr. Mike Goza tried to add the QtSerialPort support to android (for FTDI, CP, PL and other chips): https://codereview.qt-project.org/c/qt/qtserialport/+/83480 (but unsuccessfull). There are used the USB API, directly. But, you can take the FTDI example provided by @Pablo-J-Rogina , if it will be simpler.

If you have it working now please mark the thread as solved so that other forum users may know a solution as been found :-)

You're welcome :)

@jsulm It worked! I already had libxcb-util0 installed but that didn't work with Qt6, so I manually installed libxcb-util1 and it works perfectly, thanks!

@qcoderpro said in Setting "focus" true in multiple elements: I need to know that process The process is called "cross compiling". You can for example tale a look at this: https://stackoverflow.com/questions/897289/what-is-cross-compilation

@jsulm That is correct, but I'd first try with the latest Qt 5 version 5.15.2 Regards

hah, I found the solution now. There is something wrong with distance field text rendering. This probleam occurs in my embedded system, and behaves well on PC. After setting "export QML_DISABLE_DISTANCEFIELD=true", the probleam is solved. see more:https://www.qt.io/blog/2011/07/15/text-rendering-in-the-qml-scene-graph The article is hard to understand, does anyone has other introductions about text rendering?

bump up still looking for solution

I would need assistance as well regarding this topic. I have been struggling for days now to get the cross compile to work so I am giving up. All guides I followed (around 10 different ones) led me back to the starting point. Nothing worked. Is it possible to just develop in Linux or Windows using QtQuick and then just use dependencies on Rpi to make it work? Is it really that complicated? When I run a demo QtQuick app on my Rpi I get that QtQuick is not installed. Before that it was PySide2 but that was easily solved by installing dependencies. Does anyone know what dependencies are required for QtQuick so that an app using QtQuick can run on Rpi? Me and my fellow students are under huge pressure with our senior project and we could really use some help. Thank you! We are even considering installing Ubuntu in Rpi to make it run.... :(

Looks like I can do something like this: var rectangle = Qt.inputMethod.keyboardRectangle; var keyboardPanning = rectangle.height - (view.height - rectangle.y);

@jsulm No because its waiting for user to click on ok . and at same time due to shutdown button clicked the shutdown label came . this both situation need to show at same time

@JonB JonB Thanks heaps!! ... you really helped greatly ... needless to say that I would like to contribute to these forums in return for the help that I have acquired from them.
