QT Directory tree Implementation

1 View

Depending on the description of reference [4], you can use Qtreeview or qlistview to display the directory tree.

2 Model

2.1 File System Model

Implement a System file directory tree mode, you can choose to use Qfilesystemmodel or qdirmodel[4],qt routines "Dir View Example" is a good example of a directory tree, as shown in the figure below:

Many times we only need to display the file name/directory list in the directory tree, without additional information. Reference [4] shows a method that displays only the 1th column names, not the other property columns.

2.2 Custom Model

If you want to customize the node content of the tree, you can use Qstandarditemmodel, as described in "Qstandarditemmodel memory Management".
