问题 I want an animation to be painted when an element becomes visible (is should appear smoothly, not the whole at all) I tried this states: State { name: "iconOff" when: iconOnSwitch.checked == false PropertyChanges { target: selectIconRow; visible: false } } transitions: Transition { reversible: true from: "" to: "iconOff" PropertyAnimation { properties: "x,y,visible" easing.type: Easing.InOutQuad from: selectIconRow property: "visible" } } But the selectIconRow still appears immediately How

问题 I'm working on a Qt application (in C++). Without appyling any styles, my menu looks like this: I'd like it to look like this: How do I achieve this? Either using qss, or programmatically? I already tried this, without success: menu->addAction(tr("Add"), this, SLOT(CreateNewWaypoint()))->setIconVisibleInMenu(false); Answers for both Qt4.8 and Qt5 are needed to get the full bounty! 回答1: One way to solve the problem is to use QProxyStyle: customstyle.h #ifndef CUSTOMSTYLE_H #define CUSTOMSTYLE

问题 I'm using PyQt to create a GUI application. In a view inherited from QTableView, need to detect the row the user has selected when they double click a row. The table has sorting, but no editing. How do I do it? Note - tried the doubleClicked(int) signal. It is emitted by mouse buttons, not by data cells, so it was never fired. :( Ian 回答1: I dont understand. The doubleClicked signal of the QTableView has the signature void doubleClicked ( const QModelIndex & index ) If you connect that signal

问题 Is it possible to delete items from a ListView in QML like on webOS, i.e. after swiping the entry there's "cancel" and "delete". I'd like to use Qt 4.7 (so QtQuick 1.1) 回答1: There is no default component in QtQuick that can handle gesture signals. There was a Qt labs project that introduced a GestureArea that may do what you want. It was not pacakged with QtQuick 1.1 and I am unsure as to its current status but feel free to give it a try. http://blog.qt.digia.com/blog/2010/10/05/getting-in
