说我有一个QHBoxLayout
那里有2个QTextEdit
S和它们之间的按钮有一个箭头向右。当你点击按钮时,右边的QTextEdit
通过移动左边框逐渐关闭,直到它遇到正确的边框。同时,左边QTextEdit
的右边框取右边QTextEdit
发布的地方。按下按钮后,系统的状态即将到达前一个状态。QWidget的 - 调整动画
编辑:为了组织本我也做了以下内容:
1)在头文件:
class MyWidget : public QWidget
{
Q_OBJECT
QTextEdit *m_textEditor1;
QTextEdit *m_textEditor2;
QPushButton *m_pushButton;
QHBoxLayout *m_layout;
int m_deltaX;
public:
MyWidget(QWidget * parent = 0);
~MyWidget(){}
private slots:
void closeOrOpenTextEdit2(bool isClosing);
};
2)在源文件中:
MyWidget::MyWidget(QWidget * parent):QWidget(parent),m_deltaX(0)
{
m_pushButton = new QPushButton(this);
m_pushButton->setText(">");
m_pushButton->setCheckable(true);
connect(m_pushButton, SIGNAL(clicked(bool)), this, SLOT(closeOrOpenTextEdit2(bool)));
m_textEditor1 = new QTextEdit(this);
m_textEditor1->setText("AAAAA AAAAAAAAAAA AAAAAAAAAAA AAAAAAA AAAAAAAAAAA AAAAAAAAAAA AA");
m_textEditor2 = new QTextEdit(this);
m_layout = new QHBoxLayout;
m_layout->addWidget(m_textEditor1);
m_layout->addWidget(m_pushButton);
m_layout->addWidget(m_textEditor2);
setLayout(m_layout);
}
void MyWidget::closeOrOpenTextEdit2(bool isClosing)
{
QPropertyAnimation *animation1 = new QPropertyAnimation(m_textEditor2, "geometry");
QPropertyAnimation *animation2 = new QPropertyAnimation(m_pushButton, "geometry");
QPropertyAnimation *animation3 = new QPropertyAnimation(m_textEditor1, "geometry");
if(isClosing) //close the second textEdit
{
m_pushButton->setText("<");
QRect te2_1 = m_textEditor2->geometry();
m_deltaX = te2_1.width()-3;
QRect te2_2(te2_1.x()+m_deltaX, te2_1.y(), 3 ,te2_1.height());
QRect pb_1 = m_pushButton->geometry();
QRect pb_2(pb_1.x()+m_deltaX, pb_1.y(), pb_1.width() ,pb_1.height());
QRect te1_1 = m_textEditor1->geometry();
QRect te1_2(te1_1.x(), te1_1.y(), te1_1.width()+m_deltaX, te1_1.height());
//animation->setDuration(10000);
animation1->setStartValue(te2_1);
animation1->setEndValue(te2_2);
animation2->setStartValue(pb_1);
animation2->setEndValue(pb_2);
animation3->setStartValue(te1_1);
animation3->setEndValue(te1_2);
}
else //open
{
m_pushButton->setText(">");
QRect te2_1 = m_textEditor2->geometry();
QRect te2_2(te2_1.x()-m_deltaX, te2_1.y(), 3+m_deltaX ,te2_1.height());
QRect pb_1 = m_pushButton->geometry();
QRect pb_2(pb_1.x()-m_deltaX, pb_1.y(), pb_1.width() ,pb_1.height());
QRect te1_1 = m_textEditor1->geometry();
QRect te1_2(te1_1.x(), te1_1.y(), te1_1.width()-m_deltaX, te1_1.height());
//animation->setDuration(10000);
animation1->setStartValue(te2_1);
animation1->setEndValue(te2_2);
animation2->setStartValue(pb_1);
animation2->setEndValue(pb_2);
animation3->setStartValue(te1_1);
animation3->setEndValue(te1_2);
}
animation1->start();
animation2->start();
animation3->start();
}
编辑:
而且我有以下问题:
当我关闭第二QTextEdit
(通过点击按钮),调整MyWidget
,那么QTextEdit
恢复其状态(但应保持关闭状态,当然)。我怎么解决这个问题?
请为我提供一段代码。
也许你的解决方案的描述,而不是高度特定于你的情况代码,对于其他人在SO上会更有帮助 – Troyseph 2015-04-15 13:41:12
