![]() ![]() Because of this each cell delegate does NOT have access to any of the roles for the given data entry and only has access to the single role this can be a source of pain requiring work a rounds in some cases so keep it in mind. Note here that like the TableView each cell delegate is acting on a role and NOT a data entry. Take-away: Don’t anchor the left hand side of your item delegate root when using TreeViews. ![]() Once I removed the offending anchor all was right with the world again. Turns out the TreeView does not like this as it tries to indent the leafs under the parent. It took me a bit to figure out that it was this anchoring that broke my view. Then define a ListView as follows you’ll get the following on screen when you run your application:Ĭolor: ( index % 2 = 0 ) ? "white" : "lightblue"Īnchors // BOOĪnchors.verticalCenter: parent.verticalCenter So if you create a model which stores its data like so: The ListView is used to present data stored in a model in the form of a list and can use either the ListModel QML type, which stores data in the form of a list as its name implies, or a derivative of the QAbstractItemModel. Explanation of Qt Quick Viewsįirst let me quickly explain the existing two views which are among the most commonly used views in Qt Quick. In Qt Widgets you have QListView, QTableView, and QTreeView however in Qt Quick you only have ListView and TableView (where the TableView is really under the hood multiple ListViews (one for each column) wrapped in a nice API to make it look like a table) but no TreeView… until today. You may be asking wait Qt’s had a tree view for a while now, that is you’d be saying that if you’ve never played with Qt Quick. #QT QUICK TABVIEW HOW TO#In this tutorial I’m going to show you how to use the new TreeView to present data which is organized in a tree. One of the new arrivals in this version is the much sought after TreeView QML type. On July 1st Qt release version 5.5 which included a number of improvements and new additions to the framework. ![]()
