如圖所示，為啥我的進度條都100了為啥還不滿呢？
#include "progressdlg.h"
ProgressDlg::ProgressDlg(QWidget *parent)

{
QFont font("ZYSong18030",12);
setFont(font);
setWindowTitle(tr("Progress"));

FileNum->setText(tr("檔案數量："));
FileNumLineEdit = new QLineEdit;
FileNumLineEdit->setText(tr("10000"));
ProgressType = new QLabel;
ProgressType->setText(tr("顯示型別"));
comboBox = new QComboBox;
comboBox->addItem(tr("ProgressDlg"));
comboBox->addItem(tr("ProgressBar"));
progressBar = new QProgressBar;
starBtn = new QPushButton;
starBtn->setText(tr("開始"));
mainLayout = new QGridLayout(this);
mainLayout->addWidget(FileNum,0,0);

mainLayout->addWidget(ProgressType,1,0);
mainLayout->addWidget(comboBox,1,1);
mainLayout->addWidget(progressBar,2,0,1,2);
mainLayout->addWidget(starBtn,3,1);
//mainLayout->setMargin(15);
// mainLayout->setSpacing(10);
connect(starBtn,SIGNAL(clicked()),this,SLOT(startProgress()));
}
void ProgressDlg::startProgress()
{
bool ok;
int num = FileNumLineEdit->text().toInt(&ok);
progressBar->setRange(0,num);
for (int i = 1;i < num+1;i++) {
progressBar->setValue(num);
}
}
ProgressDlg::~ProgressDlg()
{
}

用樣式了造成的吧？uj5u.com熱心網友回復：
我用你的程式試驗了一下,沒有問題!

void ProgressDlg::startProgress(){
bool ok;
int num = FileNumLineEdit->text().toInt(&ok);
progressBar->setRange(0,num);
QCoreApplication::processEvents();
for (int i = 0;i < num+1;i++) {
progressBar->setValue(i);
QCoreApplication::processEvents();
}
}

3樓的方法我嘗試了，還是沒有用列uj5u.com熱心網友回復：
牛啤,我想要弄出你這種效果,都沒辦法uj5u.com熱心網友回復：
QProgressBar設定值為100，就應該填充滿。之所以沒有滿，應該是設定了stylesheet，可以去掉試試，或者看看布局，放到單獨的布局中試試轉載請註明出處，本文鏈接：https://www.uj5u.com/yidong/18847.html
