Question

根据QT4文档，默认情况下，QDialog的sizeGrip被禁用，但无论如何我都有。所以我尝试运行setSizeGripEnabled（false），我仍然有一个。所以，其他一些必须导致这一点，但我不知道是什么。如果重要，我的对话框目前没有父对象，因为我正在设计/测试它。我不明白为什么这应该重要，但只是提到它，以防它出于某种原因。这是我的完整代码：

#include "QtGui"
//#include "clposter.h"

void add_new_account()
{
    // CHECK::Make sure this process is destroyed when it's supposed to be
    // TODO::connect signals to slots
    //
    // Create Dialog box to add user account
    QDialog *accountDialog = new QDialog();
    accountDialog->setModal(true);
    accountDialog->setWindowTitle("Add New Account");
    accountDialog->setSizeGripEnabled(false);

    // Create Main Layout
    QVBoxLayout *mainVBox = new QVBoxLayout(accountDialog);

    QLabel *accountNameLabel = new QLabel(accountDialog);
    accountNameLabel->setText("Account:");
    QLineEdit *accountName = new QLineEdit(accountDialog);
    accountName->setMinimumWidth(250);
    QLabel *accountPassLabel = new QLabel(accountDialog);
    accountPassLabel->setText("Password:");
    QLineEdit *accountPass = new QLineEdit(accountDialog);
    accountPass->setEchoMode(QLineEdit::Password);

    // NOTE::May want to use standard dialog buttons instead
    QPushButton *okButton = new QPushButton("Ok", accountDialog);
    QPushButton *cancelButton = new QPushButton("Cancel", accountDialog);

    // Connect signals to slots

    // Set layout
    // CHECK::Should accountDialog be the parent for these? I get a warning that they cannot be set
    //        because accountDialog already has a layout, which is expected, but I want them to
    //        automatically be deleted when accountDialog is so it makes sense to make it the parent.
    QVBoxLayout *labelsVBox = new QVBoxLayout(accountDialog);
    labelsVBox->addWidget(accountNameLabel);
    labelsVBox->addWidget(accountPassLabel);

    QVBoxLayout *lineEditsVBox = new QVBoxLayout(accountDialog);
    lineEditsVBox->addWidget(accountName);
    lineEditsVBox->addWidget(accountPass);

    QHBoxLayout *topHBox = new QHBoxLayout(accountDialog);
    topHBox->addLayout(labelsVBox);
    topHBox->addLayout(lineEditsVBox);

    QHBoxLayout *buttonHBox = new QHBoxLayout(accountDialog);
    buttonHBox->addStretch();
    buttonHBox->addWidget(okButton);
    buttonHBox->addWidget(cancelButton);

    mainVBox->addLayout(topHBox);
    mainVBox->addLayout(buttonHBox);

    accountDialog->setLayout(mainVBox);

    // Show Dialog
    accountDialog->exec();
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    //CLPoster mainWin;
    //mainWin.show();
    add_new_account();

    return app.exec();
}

设置父级不应影响任何内容。

您可以通过使用setFixedSize（width，height）将Dialog设置为固定大小来解决此问题;

然而，这绝对是一种解决方法。

为什么我不能将QDialog设置为没有sizeGrip？
