QTransposeProxyModel Class▲

  • Header: QTransposeProxyModel

  • Since: Qt 5.13

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS Core)

    target_link_libraries(mytarget PRIVATE Qt6::Core)

  • qmake: QT += core

  • Inherits: QAbstractProxyModel

Detailed Description▲

This model will make the rows of the source model become columns of the proxy model and vice-versa.

If the model is a tree, the parents will be transposed as well. For example, if an index in the source model had parent `index(2,0)`, it will have parent `index(0,2)` in the proxy.
