Question

我有一个QGraphicsTextItem表现为lineedit，使用

setTextInteractionFlags(Qt::TextEditorInteraction);

但是，如果用户按下输入，它将显示多行。我希望它忽略换行，怎么做？

Answer 1

AFAIK QGraphicsTextItem没有实现该功能。您可以通过继承QGraphicsTextItem并过滤键盘事件来实现这一目的：

App.controller('InviteController', function ($scope, $rootScope, $routeParams, $location, UserServices) {
$scope.init = function () {
    console.log("hii this is a test ")
};


$scope.email = {};

$scope.AddToInviteList = function () {

    UserServices.AddToInviteList($scope.email, function (dataresponse) {


        console.log(dataresponse);

    })

}

我最终使用以下代码。和@wasthishelpful一样的想法。

class GraphicsLineEditItem : public QGraphicsTextItem {
    Q_OBJECT
public:
    explicit GraphicsLineEditItem(QGraphicsItem *parent = 0) : QGraphicsTextItem(parent)
    { setTextInteractionFlags(Qt::TextEditorInteraction); }

signals:
    void returnPressed();

protected:
    void keyPressEvent(QKeyEvent *event) {
        switch (event->key()) {
        case Qt::Key_Return:
        case Qt::Key_Enter:
            emit returnPressed();
            break;
        default:
            QGraphicsTextItem::keyPressEvent(event);
        }
    }
};

如何制作QGraphicsTextItem单行？
