我希望能够在我的脚本中接受强制和可选标志.这是我到目前为止所拥有的.

#!bin/bash

while getopts ":a:b:cdef" opt; do
      case $opt in
        a ) APPLE="$OPTARG";;
        b ) BANANA="$OPTARG";;
        c ) CHERRY="$OPTARG";;
        d ) DFRUIT="$OPTARG";;
        e ) EGGPLANT="$OPTARG";;
        f ) FIG="$OPTARG";;
        \?) echo "Invalid option: -"$OPTARG"" >&2
            exit 1;;
        : ) echo "Option -"$OPTARG" requires an argument." >&2
            exit 1;;
      esac
    done
echo "Apple is "$APPLE""
echo "Banana is "$BANANA""
echo "Cherry is "$CHERRY""
echo "Dfruit is "$DFRUIT""
echo "Eggplant is "$EGGPLANT""
echo "Fig is "$FIG""

但是,输出如下:

bash script.sh -a apple -b banana …

For the life of me, I cannot find the setting that allows changes to Smart Highlighting in Qt Creator. See the image below for an example. When I click the start variable, Qt Creator puts a box around other occurrences of the variable. Where is the setting to change the background color of these highlights?

Thanks in advance.

我有一个有3个主要小部件的应用程序.我也有一个弹出窗口QDockWidget.我正试图QDockWidget将底部停靠在底部小部件的右半部分,但正如您在下图中看到的那样,我可以停靠窗口的唯一位置是应用程序的边缘.我怎样才能使QDockWidget窗口占据底部小部件的右半部分？

此外,有没有办法QDockWidget在打开应用程序时已经停靠,而不是让它在自己的窗口中单独打开？

编辑:在下面使用@ Bertrand的答案,这是我最后做的事情:

我想设置一个QTimer在我的程序中运行的函数。我有以下代码：

// Redirect Console output to a QTextEdit widget
new Q_DebugStream(std::cout, ui->TXT_C); 

// Run a class member function that outputs Items via cout and shows them in a QTextEdit widget
// I want to set up a QTimer like the animation below for this.
myClass p1;
p1.display("Item1\nItem2\nItem3", 200);

// show fading animation of a QTextEdit box after 1000 milliseconds
// this works and will occur AFTER the QDialog shows up no problem.
QGraphicsOpacityEffect *eff = new QGraphicsOpacityEffect(this);
ui->TXT_C->setGraphicsEffect(eff); …
