@MHermann Others will know more than I. Just some thoughts. Just how big is "big"? MBs? GBs? I can imagine/guess that after the initial setting of the property it will destroy its current value before replacing it with a new one. That could add (quite?) some time to copies after the first time? Is this specifically a JSON issue? If you create a property which is, say, a huge string do you see the same slow down over time? Are you able to test with the last Qt 5.15 instead of your 5.12?

@Pedro said in Forum Updated NodeBB v4.3 + New features: Profile View Now you get a profilecard snippet by hovering over a user's name/picture. * Only if logged in. (Which probably makes sense, but I just thought I'd point it out. ....After logging in to get the feature working.)

In QT Design Studio, Tab Buttons are mostly for navigation within the UI, but each tab doesn’t automatically hide other content. Usually, a StackView or Loader is needed to switch visible content depending on the active tab.

@IamSumit can you reproduce the issue and share the Support Information logs. Please refer to the following Knowledge Base Article regarding how to obtain the Support Information is https://qatools.knowledgebase.qt.io/misc/collecting-support-info/collecting-support-information-linux-mac-windows/

LGTM. I just compared it to my checklist for CMake best practices (which you can read here), and I applaud you for: using subdirectories using PRIVATE (to limit scope) using functions that begin with target_ (in place of ancient/legacy habits of setting various options in a more global way)

In qnamespace.h, I add some key_code mappings : For example : enum Key { [...] KEY_CLEYVER_F1 = 0x01002122, // unused Qt keycode map for Cleyver XTremTab8 F1 Key KEY_CLEYVER_F2 = 0x01002121, // unused Qt keycode map for Cleyver XTremTab8 F2 Key [...] } And in androidjniinput, I add switches in static QKeyCombination mapAndroidKey(int key) { [...] switch (key) { case 0x00000122: // XTREMTAB f1 return Qt::KEY_CLEYVER_F1 ; [...] } I have four android keycodes : 0x121, 0x122 (for Cleyver) , 0x1a0 and 0x1a1 (for Crosscall).

Hi, I think you can use https://forum.qt.io/category/5/qt-io-webservices category for this type of question (moved there by the way). Are these in your "unread" section ? Are they marked as you following them ?
