Qt绘制进度条
本文介绍如何使用Qt绘制进度条，包括设置进度条的范围、当前进度及显示百分比等属性，并通过实例展示了如何利用QApplication::style()->drawControl进行绘制。
QStyleOptionProgressBarV2 *progressBarOption = new QStyleOptionProgressBarV2(); 进度条
progressBarOption->rect = option.rect;
progressBarOption->minimum = 0;
progressBarOption->maximum = subTaskNum;
progressBarOption->progress = finishedSubTaskNum;
int t = finishedSubTaskNum/subTaskNum;
progressBarOption->text = QString::number(t) + "%";
progressBarOption->textVisible = true;
//绘制进度条
QApplication::style()->drawControl(QStyle::CE_ProgressBar, progressBarOption, painter);
progressBarOption->rect = option.rect;
progressBarOption->minimum = 0;
progressBarOption->maximum = subTaskNum;
progressBarOption->progress = finishedSubTaskNum;
int t = finishedSubTaskNum/subTaskNum;
progressBarOption->text = QString::number(t) + "%";
progressBarOption->textVisible = true;
//绘制进度条
QApplication::style()->drawControl(QStyle::CE_ProgressBar, progressBarOption, painter);
