General and Desktop

Thank you all for your activity! I found out why my app freezes from time to time.Reading from the serial buffer has an unlimited size. When I parse messages, an error occurs in the business logic and an infinite loop appears (because there is a bad conditional for while loop) in read signal from Serial. That's why my memory in the application was increasing. I don't know why this error not occurred on Ubuntu, but I've started to fix this problem.

@buhtz The grid size is a QSize in pixels x and y, not a number of rows and columns. Items will align on this notional grid when rendered. You can leave it out and the wrapping will be compact.

@Alexey-Serebryakov I have same proplem , Have you got a solution yet?

@Tater Start by demonstrating what value this->VisiblePixmapList[(int)item->VisibilityIcon] has. It's probably correct, but we/you don't know that for sure till you print it out. Use break statements correctly and consistently in your switch statement. You are returning a QPixmap for DisplayRole. Where does Qt say you can do that? DisplayRole has to resolve to a string, https://doc.qt.io/qt-6/qt.html#ItemDataRole-enum Qt::DisplayRole 0 The key data to be rendered in the form of text. (QString) QPixmap does not, so probably comes out empty. I have not tried it, but from that page don't you want: Qt::DecorationRole 1 The data to be rendered as a decoration in the form of an icon. (QColor, QIcon or QPixmap) ?

@SGaist I have tried set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON) again but it does not seem to work for qt symbols. I get errors mentioning the static meta object

Sorry for all, after considering, this is absolutely a fake requirement. Manager Class will always add member to Document class. Avoid changes to Document class is meaningless.

@ChrisW67 , got it, thanks!

@SameerK If it's repeatable you can raise a bug report for it. They will want as small a piece of code for the UI as possible. Pick something standard under Linux for the command (sleep might be suitable).

@artwaw No, sir. I am just showing that I have placed those files in the output folders. I am showing that I have placed those in each and every place where I was told to place them above. Also, it's available in the driver folder too. But, it's ok now 😅

@jsulm Please note the OP is discussing this in https://forum.qt.io/topic/146828/update-2-qtablewidgets-simultaneously-to-reduce-the-run-time.

@Creatorczyk Just a guess from looking at the image: It looks like you made IpComboBox a QGroupBox. A QComboBox subclass widget wouldn't have it's own layout. If you want your IpComboBox in your QGroupBox, create a box, move a regular comboBox in there and promote this widget to your IpComboBox code/class

@jsulm I was just about to comment that I solved it. I just switched to the 11.0 branch instead of the master branch. I'm using Qt 6.3.1 and building Qt Creator 11.0 and now it works!
