QML and Qt Quick

@dheerendra there might be different numbers and of areas that should be blocked. I've been developing universal background for loader sign (not QML component Loader). For me it simpler to use empty function because I don't care about number and types of mouse areas.

@Praveen-Illa said in Not able to resolve std::atomic operations in Qt 5.15.2: Not resolving <iostream> and <atomic> directives Install the c++ development packages for your platform and compiler, possibly for the atomic library, drop the superfluous INCLUDEPATH+= from your project and link against the atomic library if necessary: LIBS += -latomic.

There are quite a few problems with the TreeView 2 docs - there is already post already escalating this issue. Even conceptually I'm unsure about how things work: Shouldn't a selectionMode be tied to a view? The way I read the TreeView 2 docs the ItemSelectionModel is an independant object that I add/delete items to/from. In that case why bother with the 'flags' method in QAbstractItemModel? If I need to add/remove to/from the selection model on my own, can't I just ignore those flags? As well, shouldn't 2 views allow different items be selectable? (So why associated the selectable flag with the QAbstractItemModel)

If it is in a different thread, you should use QueuedConnection for sure. This way you can be certain no thread synchronization issues occur. Or, if you leave connection type argument empty, Qt will choose the right type automatically for you (queued for threaded connections, direct otherwise). You can also use QueuedConnection in single-thread connections to delay slot execution a bit, allow the event loop to spin etc. In short: direct connection is the same as direct function call - it is called immediately and in the same thread queued connection is inserted into event loop and will be called "some time in the future, by receiving thread". Where "some time" is usually "very quickly"

@ParCHAT1497 said in Infinite scrolling of a TableView: @sierdzio Hi i want to implement something similar... i am not able to fetch the position of scrollbar.. how can I do it ? See the original post by @tezine it includes exact code you need.

I have created a SO question as well in case someone wants to answer there instead: https://stackoverflow.com/questions/64267727/qml-why-does-tabbars-implicitwidth-depend-on-binding-inner-tabbuttons-width/64330266

Turns out it was a bug: https://bugreports.qt.io/browse/QTBUG-92076

@ocgltd I don't know of any other documentation, sorry. Your best bet might be to post at the Interest mailing list (subscribe before posting). Qt engineers are active on that list.

No, you have to redraw it as setText is for metadata. What is the issue with the solution I suggested ?

What was it ?

@jsulm I meant modules such as import QtQuick 2.12 import QtQuick.Window 2.12 import QtQuick.Controls 2.15

@mzimmers Right, ListElements are a collection of roles. If you want to set "dynamically" those roles, you should play with the javascript functions of ListModel, and implement some kind of mechanism (depends on your use case) to update it.
