If we want to hide the top level node, we have to supply the parent index in a different way.
Also this behaviour is used to distinguish whether a node is at the top level. For top level nodes, the call for retrieving parent will return None (even though it is the child of the invisible root node) whereas for sublevel nodes the call will return the parent node. This is because the parent behaviour between top level and sublevel nodes is different. On the pyqt channel on freenode, virousa and frankRojas both asked for a way to create a menu for a tree view that showed different entries for items at different depths in the tree. Let say we want to hide the top level node (Branch 1) and we issue the following call:
Developers who do not need the flexibility of. This class is based on Qts Model/View architecture and uses a default model to hold items, each of which is a QTreeWidgetItem. This hides the 2nd row from the branch1 node. The QTreeWidget class is a convenience class that provides a standard tree widget with a classic item-based interface similar to that used by the QListView class in Qt 3. childidx: index of the child item under that category to select. categoryidx: index of the category to select. parent1.appendRow ( item1,item2,item3) will populate all 3 columns, to populate a second column for the parent simply set the item in the model at the desired index. Args: model: model to create a fake view for. Since the standard item model is instantiated with 3 columns the rows can be appended with an item or item (s) so. Let say we want to hide the child node B, we can simple call setRowHidden method, like below: def mockviewindex(model, categoryidx, childidx, qtbot): '''Create a tree view from a model and set the current index. Below is the screen shot with all branches expanded: Below demonstrates how the results would work when a filter. The filtering would remove top level items which dont contain children that match the filter string. I want to create a treeview with filtering.
PYQT5 TREEVIEW CODE
(True)Ībove code creates a treeview with 2 branches both with 2 child nodes. I have a more solid background in C and WPF. # -īranch1.appendRow()īranch2.appendRow() You can rate examples to help us improve the quality of examples. Lets start with a simple treeview example with two non-empty branches. These are the top rated real world Python examples of extracted from open source projects. In Qt treeview, hidding top level nodes is different to hidding lower level nodes.
