General and Desktop

@Paddle said in Making a list of widgets should be simple, yet it is dauntingly complex.: Paint manually the thumbnail, text (those 2 are not too hard) but the combobox? Do I need to draw a rectangle the text and the arrow myself? The button? No, there is this, which provides everything to style/paint a comboBox. https://doc.qt.io/qt-6/qstyleoptioncombobox.html Make a widget class for my items anyway because it's needed for the createEditor for when the user click the item such that the thing can actually be modified and not just painted? The delegate only uses the real widgets, when you "activate" it (in editing mode), otherwise it's just "flat", so it doesn't need too much resources. Here's another delegate example: https://doc.qt.io/qt-6/qtwidgets-itemviews-stardelegate-example.html

@Christian-Ehrlicher Thank you, I could able to receive WM_USER message in native event filter with the help of MFC class.

@vcasado IIRC, you need, besides the NSBluetoothAlwaysUsageDescription also the NSBluetoothPeripheralUsageDescription or I at least have both in my plist files

@Chris-Kawa Thanks~ I will check it. :)

Ensure that it has been built with MinGW. Recent versions of the Qt online installer allows you to download a suitable version of OpenSSL.

@Pl45m4 The "remote device scan" gets started and I read SIGNAL "device detected". The "remote device scan" scans for multiple devices , hence "device detected" gets posted until "scan finished" is posted. I currently have ONLY one Bluetooth adapter and that is the one used to perform "remote device scan". This "sequence" is managed by the initial "start scan ".

@JonB Hi Jon , Thanks. Right , added \ and its working. Creating the hdf file now. Thanks & warm regards, ~ Rudresh

@Christian-Ehrlicher Thank you, it helped! In fact, these two commits contained what I needed: Fix dragging a docked QDockWidget [REG-fix] 430985: Refix QDockwidget drag out dockwidget

@LusuQT said in Do an operation when computer goes to sleep: But when I put my laptop to sleep it does not capture the PBT_APMSUSPEND event. Make sure that your laptop's power management is configured the same way as the Desktop PC's. Check, if your laptop doesn't go into hibernate instead of suspend, when "going to sleep" (either by keyboard shortcut or from menu). I'm not sure if hibernate also triggers the SUSPEND event. The current power settings can also vary when using different powerplans (I think it's called like that?!). (Just a guess that this might be the difference)

@Anila If you are on Windows and need this for Windows only, have a look here: https://forum.qt.io/topic/69485/do-an-operation-when-computer-goes-to-sleep As @SGaist said, there is no platform independent "Qt way". You have to do this for every OS separately, if you are planning to go multi-platform

@Perdrix Parent-Child mechanism :) You can put any widget on top of any other widget (in its coordinate system) by setting the bottom widget as parent of the toplevel one. In this case @Chris-Kawa used a layout

QMenuBar::paintEvent() does not set the MouseOver state: https://code.qt.io/cgit/qt/qtbase.git/tree/src/widgets/widgets/qmenubar.cpp#n882 and https://code.qt.io/cgit/qt/qtbase.git/tree/src/widgets/widgets/qmenubar.cpp#n882 Looks like you have to derive from QMenuBar, override initStyleOption() and set it by your yourself.

@JoeCFD All screens displayed are on the same display and all have the same resolution of 800x480

@Dummie1138 said in QMessagebox: lack of RejectRole makes close (X) button disabled: An example elsewhere in the code where the apparent lack of RejectRole does not disable the close button. Well, there is a difference between QDialog and QMessageBox. Choose the right one for your task instead of trying to trick the wrong one into doing things it is not meant to do.
