Python Qmodelindex Internalpointer Returning Random Objects And

Python Qmodelindex Internalpointer Returning Random Objects And .internalpointer() should give me a criterionnode object, but sometimes i get corrupt data, criterionnode semi empty objects or totally random objects. i even got objects (like line2d objects) belonging to the matplotlib chart, whose logic is separated from the tree model. The cause of the issue is that pyside2 does not maintain a handle of the object so python was destroying the objects between creating the index and accessing them later.

Python Qmodelindex Internalpointer Returning Random Objects And Use internalpointer () when your model directly represents a simple c data structure like a tree of objects. it’s the most direct and efficient way to link an index to a specific item. The pyside.qtcore.qmodelindex.child () function is used to examine items held under the index in the model. the pyside.qtcore.qmodelindex.sibling () function allows you to traverse items in the model on the same level as the index. Each top level item in a model is represented by a model index that does not have a parent index in this case, will return an invalid model index, equivalent to an index constructed with the zero argument form of the qmodelindex constructor.

Qmodelindex Internalpointer Returning Random Objects And Crashing Each top level item in a model is represented by a model index that does not have a parent index in this case, will return an invalid model index, equivalent to an index constructed with the zero argument form of the qmodelindex constructor. Contribute to lineageos android kernel virt virtio development by creating an account on github. An invalid model index can be constructed with the qmodelindex constructor. invalid indexes are often used as parent indexes when referring to top level items in a model. Each top level item in a model is represented by a model index that does not have a parent index in this case, parent () will return an invalid model index, equivalent to an index constructed with the zero argument form of the qmodelindex () constructor. New qmodelindex objects are created by the model using the qabstractitemmodel::createindex () function. an invalid model index can be constructed with the qmodelindex constructor. invalid indexes are often used as parent indexes when referring to top level items in a model. When you call internalpointer () on a qmodelindex, the “object” that was assigned in the call to createindex () is the one that will be returned. every index in your model must have a unique combination of (row, column, object).
