内容:
我想改变默认的按钮颜色和按钮上字体的颜色，我用的是qt2.3.7，请问能实现么
我尝试了一下uclinux发的改变按钮字体颜色的方法
QPushButton pushbutton("hello world");
.......
.......
.......
QPalette newPalette = pushbutton.palette();
newPalette.setColor(QPalette::ButtonText, Qt::blue);
pushButton.setPalette(newPalette);
但是编译时提示没有ButtonText成员：（
#1 [style 09-20 16:28]
QPushButton pushbutton("hello world");
.......
.......
.......
QColor newColor = ("blue");
QColorGroup new = palette().copy().normal();
new.setColor(ColorGroup::ButtonText, QColor("blue"));
QPalette newp;
newp.setNormal(new);
setPlalette(newPalette.true);

我按你的方法敲进去了，出现了语法错误
QColorGroup new = palette().copy().normal();和 newp.setNormal(new);
还有 setPalette(newp,true);这三句有问题
#3 [style 09-20 20:05]
我写的是QT3的.
我没QT2文档.所以不知道相关函数名和参数.
我只是大概意思.你看懂我的这段代码意思就行了.最主要是你写的代码思路就不对.
QPalette::ButtonText
QPalette分4种模式, (QT4中,好像在QT3中只分3种)
QPalette::Disabled
QPalette::Active
QPalette::Inactive
QPalette::Normal
而你写的ButtonText是QColorGroup的emun成员
#4 [style 09-20 20:06]
emun->enum

谢谢style，不过我刚学习qt没多久不太会查文档，你写的语句我有些看不懂，比如QColorGroup new = palette().copy().normal(); newp.setNormal(new); setPlalette(newPalette.true);我现在只能照着现有的例程编点软件呵呵。麻烦你给我详细解释下好么，谢谢你
我把QPalette.h贴出来吧
