啊？？？我怎么没在Qt 4.0.1的Qt Assistant里找到QMultiLineEdit这个类？楼主所说的是Qt 3.x里面的？
#2 [girl2008 08-29 14:35]
我用的是qt-2.3.7的，后续的版本都是用的ＱＴＥＸＴＥＤＩＴ，没有ＱＴＭＵＬＴＩＬＩＮＥＥＤＩＴ这个类了

基本原理就是：截取它的KeyPress事件，然后识别它的按键，如果是tab的话，就忽略。
源代码如下：
#include
#include
#include
class MyTextEdit:public QTextEdit
{
public:
MyTextEdit(QWidget *parent = 0);
~MyTextEdit();
private:
void keyPressEvent(QKeyEvent *event);
void keyReleaseEvent(QKeyEvent *event);
};
MyTextEdit::MyTextEdit(QWidget *parent)
:QTextEdit(parent)
{
}
MyTextEdit::~MyTextEdit()
{
}
void MyTextEdit::keyPressEvent(QKeyEvent *event)
{
if (event->key() == Qt::Key_Tab)
{
event->ignore();
}
else
{
QTextEdit::keyPressEvent(event);
}
}
void MyTextEdit::keyReleaseEvent(QKeyEvent *event)
{
if (event->key() == Qt::Key_Tab)
{
event->ignore();
}
else
{
QTextEdit::keyReleaseEvent(event);
}
}
int main(int argc, char **argv)
{
QApplication app(argc, argv);
MyTextEdit textedit;
textedit.resize(600, 400);
textedit.show();
return app.exec();
}

我之前试过，tab是没有起作用，但是我现在想要它tab键后跳转到下一个控件，像lineedit一样，试过不行，我再去看看。。。。谢谢XChinux了~！！！

嘿嘿，刚才我试验的，把TextEdit里的tab键屏蔽了之后，它自动就设为Taborder了，自动跳转到下一个部件了。
