|
|
``` cpp
|
||
|
|
void MainWindow::initFont()
|
||
|
|
{
|
||
|
|
int font_id = QFontDatabase::addApplicationFont(":/font/SourceHanSansCN-Medium.otf");
|
||
|
|
if(font_id != -1){
|
||
|
|
//获取导入的字体文件中，有几种字体样式，比如字体文件中存在粗体和普通字体样式，需要逐一设置
|
||
|
|
QStringList fontFamilies = QFontDatabase::applicationFontFamilies(font_id);
|
||
|
|
foreach (QString fontFamily, fontFamilies)
|
||
|
|
{
|
||
|
|
qDebug() << "MainWindow.initFont.fontFamily:" << fontFamilies;
|
||
|
|
// 设置字体
|
||
|
|
QFont font(fontFamily);
|
||
|
|
qApp->setFont(font);
|
||
|
|
}
|
||
|
|
}else{
|
||
|
|
qWarning() << "Font init failed!";
|
||
|
|
qApp->setFont(QFont("微软雅黑"));
|
