kandi X-RAY | tree-model Summary

tree-model is a C++ library typically used in Utilities, Build Tool applications. tree-model has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

Example of a hierarchical tree model in Qt. The example uses Qt 5 and libxml2 (via libxxxml) to work on XML trees and libxfsx to work on binary files encoded in the BER ASN.1 flavour. It implements an abstract tree model and provides an adaptor to QAbstractItemModel. In addition to that, a generic Undo/Redo class interfaces with QAbstractItemModel. An example GUI editor is included to demonstrate the model in action with XML and ASN.1 BER files. Each class has several unittest test cases. Besides catching errors and regressions, they can also be consulted as examples how the different APIs are intended to be used. 2016, Georg Sauthoff mail@georg.so.

After loading the data you fill $scope.dataForTheTree. Then you can walk through the tree and set the root of each node. I coded this for you using a var dataForTheTree with your example data. After running the below, each node has a root property set with it's root node.

Even though angular-tree-control readme says:

Include context-menu module if you're going to use menu-id attribute

How to use PyQt5 QCompleter for code completion

Asked 2018-Apr-20 at 02:11

I want to create a QLineEdit field with basic code completion capability, but so far whenever I select an attribute of an item item.attr, the item. is replaced by attr rather than inserting attr after item.. Furthermore if that attr has attr.subattr, it is impossible to predict it because item. has been replaced and attr. does not exist at the root of my model.

I have created a relatively minimal example:

...

ANSWER

Answered 2018-Apr-20 at 00:35

The pathFromIndex() method returns the string that will be placed in the QLineEdit, instead it will return the concatenation of the text of the item and the texts of its predecessors. To make it more efficient and not calculate that online concatenation, a new role will be created to the model that contains that data.

Nice tree.

To fix the texturing, first update the proctree.js to three.js conversion code to use the tree.uvsTwig array, instead of tree.UV, for the twigs:

Install tree-model

CMake is used - cmake usually makes it easy to build C++ projects, but the CMake Qt support is relatively new, is not extensively documented and there are some tutorials available that use deprecated cmake Qt commands. There are also pitfalls, e.g. if you use namespaces and want to generate Qt moc files for classes with the same name that are located in different namespaces. As of 2015, this yields collisions if you use CMAKE_AUTOMOC ON. Similar issues occur with .ui files, only worse - even if you omit CMAKE_AUTOUIC, all files are still generated in the top level build directory.

Qt has a class for interacting with the system's clipboard in a portable fashion. When dealing with QAbstractItemModels it is natural to also use the drag-and-drop related methods dropMimeData() and mimeData() to paste and copy the clipboard data. The adaptor model thus also implements them and translates them into equivalent calls of the tree_model::Base model. Using XML as the serialization format of the clipboard has the advantage that it is human readable and can be easiliy changed with a normal text editor. When multiple elements should be copied or inserted one has to decide how to map that to XML since an XML document may only have one root. One possibility is to create an artificial root element that is part of the mime data. The editor example implements a variation. The serialized XML is just a concatenation of serialized subtrees, thus, not necessarily a valid XML document as such. But, on deserialization the document is implicitly wrapped with an artificical root element such that an off-the-shelf XML parser can be used (after insert that root is discarded). With the Qt clipboard API one has to decide which clipboards to support exactly. For example under X11, there is the primary selection buffer and a normal clipboard. Also, a clipboard may contain a document in several versions (with different mime types). The editor example thus exports a copied selection multiple times: into the selection buffer, into the normal clipboard as normal text and with mime-type 'text/xml'. The normal text copy is done because this is what normal text editor request; such that the 'text/xml' version is ignored. The mime-type 'text/xml' is what is expected by the editor - also for drag-and-drop operations. The X11 selection copy is done for convenience, e.g. to easily paste something into a terminal window.
