Then it's a good first step so you will get these extra find modules for cmake which contains one for poppler. Otherwise, use CMake's find_library and find_path functions.

@Leyu the Linux framebuffer platform doesn't natively support window decorations such as title bars. I guess it is not hard to create your own titlebar.

Awesome, that did it, thank you!

@tankist You could split your whole app into two components. One non GUI or non Qt background/ console program and one Qt GUI part which is responsible for the system tray menu.

@gabello306 said in Capturing mouseEvents: Any ideas? Maybe because you've overridden the mousePressEvent? Do you call inherited mousePressEvent in your mousePressEvent?

@Bonnie thanks a lot It is indeed a 12.5-fold relationship.

The QWindow::activeChanged signal allows me to call the delegate function when the window is actually activated.

What exactly did you download ? "Some zip file somewhere on GitHub" does not telle what you got. Based on the error message you don't have the full sources. If you want them you better download them from the official archives.

Hi, Beside what my fellows correctly pointed (nothing widgets related should be put into a model and QWidget is the base class for anything widget), you seem to need a custom vizualization of your data. If that is indeed the case, then the correct class to check is QStyledItemDelegate. That said, you still haven't really explained your goal and what exactly you want to show. It really seems that you want your text to be shown in the center of a cell which really does not require all the complexity you are describing.

Hi, You might want to compile it yourself. 5.15.2 is x86_64 only so while it can work thanks to Rosetta you'll have trouble with external librairies.

QIcon icon(":/path_to_icon"); icon.addFile(":/path_to_icon", {}, QIcon::Selected); listItem->setIcon(icon); Tested on qt 5.15 in QListWidget.

@Pl45m4 Here is a short video of the application showing the issue: https://github.com/letsfindaway/OpenBoard/issues/203#issuecomment-2595705681 The rubber is a pixmap cursor using QCursor. The circle is repositioned at each mouseMoveEvent. You see that it is lagging behind the cursor. The preview image to the left is the second view attached to the same scene. So you see, nothing complicated. And as I already said in the beginning: when I run the same program using Qt5, then the lag is much smaller, because the repetition rate of the mouseMoveEvents is higher. I have setMouseTracking(true), so that I get the events even when the mouse button is not pressed. And no, there are no further actions connected to the movement as long as the mouse button is not pressed.

Hi! Is there any better solution for this problem, or still is this the best way?

Then there's the good old: comment out everything and add things back until it breaks.

I found out that this issue is causing the latest Windows SDK - 10.0.26100.0: https://discussions.unity.com/t/info-link-fatal-error-lnk1181-cannot-open-input-file-ucrt-lib-hololens-2-build-issue/950584/3 So, I used the following Windows SDK: 10.0.22621.0 and run: "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvars32.bat" 10.0.22621.0 Now, it completed the configuration and I successfully built Qt 5.15.16 for winrt-arm-msvc2019 architecture. This issue is resolved. Thanks.

@jsulm okay thanks I tried it and it worked. qt-online-installer-windows-x64-4.8.1.exe --mirror http://qt.mirror.constant.com

I think I've got it, I look at the parent container's arrows (BigCat's arrows). Anything connected to the nodes I'm moving might trigger updates (in the case of setPos). This is a nice way, because I can be sure I have everything and it's iterative / without signals/slots. For the child added / removed it's the same principal.

ok, I kinda get it now. I can just add spacers left and right and set fixed widths to get what I wanted. Namely, 8 80x80 pixel tiles packed together and centered along the middle of the 1600px width which is the middle of the 2 videos. [image: a76c4b24-f511-4a8e-af73-7c00637a78be.png] this gets me what I wanted: category_label = QLabel("Ball Flight\nDetails") category_label.setFixedSize(200, 80) category_label.setAlignment(Qt.AlignmentFlag.AlignRight | Qt.AlignmentFlag.AlignVCenter) category_label.setStyleSheet("font-weight: bold;") self.infoGrid.addWidget(category_label, 0, 0, 1, 1) categories = ["Club\nSpeed", "Attack\nAngle", "Spin\nRate", "Carry\nDistance", "Club\nPath", "Face\nto Path", "Side\nSpin", "Back\nSpin"] values = [128, 15, 3000, 250, 270, 30, 200, 2500] hSpace = QWidget(); hSpace.setSizePolicy(QSizePolicy.Policy.Expanding, QSizePolicy.Policy.Minimum) self.infoGrid.addWidget(hSpace, 0, 1) row = 0 for i in range(len(categories)): col=i+2 print(f"Adding content at {row},{col}") tile_widget = QWidget() tile_widget.setFixedSize(80, 80) tile_layout = QVBoxLayout(tile_widget) tile_layout.setContentsMargins(0,0,0,0) tile_layout.setSpacing(0) name_label = QLabel(categories[i]) name_label.setAlignment(Qt.AlignmentFlag.AlignCenter| Qt.AlignmentFlag.AlignBottom) name_label.setStyleSheet("font-weight: bold; color: black;") value_label = QLabel(str(values[i])) value_label.setAlignment(Qt.AlignmentFlag.AlignCenter| Qt.AlignmentFlag.AlignTop) value_label.setStyleSheet("font-weight: bold; font-size: 24px; color: white;") tile_layout.addWidget(name_label) tile_layout.addWidget(value_label) tile_widget.setStyleSheet("border: 1px solid lightblue; background-color: lightblue; border-radius: 10px;") self.infoGrid.addWidget(tile_widget, 0, col, alignment=Qt.AlignmentFlag.AlignHCenter|Qt.AlignmentFlag.AlignVCenter) hSpace = QWidget(); hSpace.setFixedWidth(470) hSpace.setSizePolicy(QSizePolicy.Policy.Expanding, QSizePolicy.Policy.Minimum) self.infoGrid.addWidget(hSpace, 0, 10)

@Pl45m4 Yeah forgot to set opacity to something else than 1, that solved it...
