wx.lib.agw.hypertreelist.HyperTreeList

HyperTreeList is a generic widget that combines the multicolumn features of a wx.ListCtrl with the hierarchical features of a wx.TreeCtrl This class does not rely on native native controls, as it is a full owner-drawn tree-list control.

It manages two widgets internally:

• TreeListHeaderWindow displays the column headers.

• TreeListMainWindow is the main tree list based off CustomTreeCtrl.

These widgets can be obtained by the GetHeaderWindow and GetMainWindow methods respectively although this shouldn’t be needed in normal usage.

AddColumnInfo(self, colInfo)

Appends a column to the HyperTreeList.

Parameters:

colInfo – an instance of TreeListColumnInfo.

---

CalculateAndSetHeaderHeight(self)

Calculates the best header height and stores it.

---

CreateEditCtrl(self, item, column)

Create an edit control for editing a label of an item. By default, this returns a text control.
