看着ie9 、firefox ，opera都效仿tab风格，对比了下，chrome的窗口上面部分还不够小，
干脆把地址栏去掉，按F10或ALT键，显示隐藏地址栏，
这里是我编译好的程序，喜欢的拿走（26M）
研究了下代码，更改如下：
1、src\chrome\browser\ui\browser.h中
//加入一个变量,记录当前 toolbar的显示状态
bool toolbar_visible_;
2、src\chrome\browser\ui\browser.cc中
//构造函数中，给变量赋值
Browser::Browser(Type type, Profile* profile)
: type_(type),
toolbar_visible_(false),
...
---------------------------------------------
//修改SupportsWindowFeatureImpl函数中代码
bool Browser::SupportsWindowFeatureImpl(WindowFeature feature,
bool check_fullscreen) const {
...
if (type() == TYPE_NORMAL && toolbar_visible_==true)
features |= FEATURE_TOOLBAR;
if ((type() & Browser::TYPE_APP ) == 0 && toolbar_visible_==true)
features |= FEATURE_LOCATIONBAR;
...
---------------------------------------------
//FocusAppMenu函数中修改代码
void Browser::FocusAppMenu() {
UserMetrics::RecordAction(UserMetricsAction("FocusAppMenu"), profile_);
//:ningth
toolbar_visible_ = !toolbar_visible_;
window_->FocusAppMenu();
}
3、src\chrome\browser\ui\views\frame\browser_view.cc中
//修改FocusAppMenu中代码
void BrowserView::FocusAppMenu() {
// Chrome doesn\'t have a traditional menu bar, but it has a menu button in the
// main toolbar that plays the same role. If the user presses a key that
// would typically focus the menu bar, tell the toolbar to focus the menu
// button. If the user presses the key again, return focus to the previous
// location.
//
// Not used on the Mac, which has a normal menu bar.
//:ningth
Layout();
SetFocusToLocationBar(true);
/*if (toolbar_->IsAppMenuFocused()) {
RestoreFocus();
} else {
SaveFocusedView();
toolbar_->SetPaneFocusAndFocusAppMenu(last_focused_view_storage_id_);
}*/
}
4、src\chrome\browser\ui\views\frame\browser_view_layout.cc中
修改LayoutToolbar函数中的height值
int BrowserViewLayout::LayoutToolbar(int top) {
int browser_view_width = vertical_layout_rect_.width();
bool visible = browser_view_->IsToolbarVisible();;
toolbar_->location_bar()->SetFocusable(visible);
int y = top;
if (!browser_view_->UseVerticalTabs()) {
y -= ((visible && browser_view_->IsTabStripVisible()) ?
kToolbarTabStripVerticalOverlap : 0);
}
int height = visible ? toolbar_->GetPreferredSize().height() : 1;
toolbar_->SetVisible(visible);
toolbar_->SetBounds(vertical_layout_rect_.x(), y, browser_view_width, height);
return y + height;
}
