本文介绍了QWidget的 - 调整动画的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
说我有一个 QHBoxLayout，负责，其中有2 的QTextEdit 和它们之间用箭头按钮对。当你点击该按钮，右侧的QTextEdit 逐渐被直到它符合正确的移动左边框关闭。同时，左边的的QTextEdit 的右边框采用该权利发布的QTextEdit 的地方。和之后的按钮pressing，系统的状态来前者
Say I have a QHBoxLayout where there are 2 QTextEdits and between them a button with an arrow to the right. When you click on the button, the right-side QTextEdit gradually closes by moving the left border until it meets the right one. Simultaneously, the right border of the left QTextEdit takes the place which the right QTextEdit released. And after pressing on the button, the state of the system is coming to the former one.
编辑：为了组织这个我也做了以下内容：
In order to organize this I have done the following:
1）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：
2) In the source file:
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：
和我有以下问题：
当我关闭第二的QTextEdit （通过点击按钮），调整进myWidget ，那么< $ C $ç>的QTextEdit 恢复其状态（但应保持关闭状态，当然）。我怎样才能解决这个问题？
When I close the second QTextEdit (by clicking on the button) and resize the MyWidget, then the QTextEdit restores its state (but it should stay closed of course). How can I solve this problem?
请为我提供一个code片段。
Please provide me with a code snippet.
推荐答案
下面是我想要的：
头文件
class MyWidget : public QWidget
{
Q_OBJECT
QTextEdit *m_textEditor1;
QTextEdit *m_textEditor2;
QPushButton *m_pushButton;
QHBoxLayout *m_layout;
QVBoxLayout *m_buttonLayout;
int m_deltaX;
bool m_isClosed;
public:
MyWidget(QWidget * parent = 0);
~MyWidget(){}
void resizeEvent( QResizeEvent * event );
private slots:
void closeOrOpenTextEdit2(bool isClosing);
};
源文件
MyWidget::MyWidget(QWidget * parent):QWidget(parent),m_deltaX(0)
{
m_pushButton = new QPushButton(this);
m_pushButton->setText(">");
m_pushButton->setCheckable(true);
m_pushButton->setFixedSize(16,16);
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_buttonLayout = new QVBoxLayout();
m_buttonLayout->addWidget(m_pushButton);
m_buttonLayout->addItem( new QSpacerItem(1, 1, QSizePolicy::Minimum, QSizePolicy::Expanding) );
m_layout = new QHBoxLayout;
m_layout->addWidget(m_textEditor1, 10);
m_layout->addSpacing(15);
m_layout->addLayout(m_buttonLayout);
m_layout->setSpacing(0);
m_layout->addWidget(m_textEditor2, 4);
setLayout(m_layout);
resize(800,500);
}
void MyWidget::closeOrOpenTextEdit2(bool isClosing)
{
m_isClosed = isClosing;
QPropertyAnimation *animation1 = new QPropertyAnimation(m_textEditor2, "maximumWidth");
if(isClosing) //close the second textEdit
{
m_textEditor2->setMaximumWidth(m_textEditor2->width());
int textEdit2_start = m_textEditor2->maximumWidth();
m_deltaX = textEdit2_start;
int textEdit2_end = 3;
animation1->setDuration(500);
animation1->setStartValue(textEdit2_start);
animation1->setEndValue(textEdit2_end);
m_pushButton->setText("<");
}
else //open
{
int textEdit2_start = m_textEditor2->maximumWidth();
int textEdit2_end = m_deltaX;
animation1->setDuration(500);
animation1->setStartValue(textEdit2_start);
animation1->setEndValue(textEdit2_end);
m_pushButton->setText(">");
}
animation1->start();
}
void MyWidget::resizeEvent( QResizeEvent * event )
{
if(!m_isClosed)
m_textEditor2->setMaximumWidth( QWIDGETSIZE_MAX );
}
