如何在QTabWidget Qt中扩展选项卡 [英] How to expand tabs in QTabWidget Qt

问题描述

我有一个像这样的QTabWidget:

但是我想扩展选项卡以填充"整个小部件宽度，如下所示:

But I want to expand the tabs to "fill" the entire widget width, like this:

我该怎么做?

我正在使用 Qt 5.3.2 和 Qt Creator 3.2.1

更新:

我尝试使用setExpanding函数:

ui->myTabWidget->tabBar()->setExpanding(true);

但这没用.

推荐答案

正如mostefa回答的那样

As mostefa answered here, I can set a fixed width for the tabs using styleSheet.

我正在根据QTabWidget宽度计算宽度.

I am calculating the width based on the QTabWidget width.

要正确获取QTabWidget宽度，我需要在showEvent函数中获取它:

To get the QTabWidget width correctly I need to get it in the showEvent function:

void LogListForm::showEvent(QShowEvent *ev)
{
    /*
     * Divide by 2 because we have 2 tabs.
     * I need to decrease 24 pixels to fill the width correctly.
     */
    int tabWidth = (ui->myTabWidget->width()/2)-24;

    /*
     * Then, I set this tabWidth to the styleSheet.
     * Note: I need to set the previously styleSheet to not lose it
     */
    ui->myTabWidget->setStyleSheet( ui->myTabWidget->styleSheet() +
                                    "QTabBar::tab {"
                                    "width: " + QString::number(tabWidth) + "px; }" );
}
