功能区菜单空白区域

Question

我在wxFormbuilder中创建了这个简单的wxWidgets应用程序：

如您所见，功能区菜单选项卡上有一个奇怪的空白区域。有什么我想念的吗？将功能区菜单直接对齐到左上角肯定会更好。如果有人想要它，这里是由wxFormbuilder生成的代码：

this->SetSizeHints( wxSize( 183,146 ), wxDefaultSize );

wxBoxSizer* bSizer4;
bSizer4 = new wxBoxSizer( wxVERTICAL );

m_ribbonBar1 = new wxRibbonBar( this, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxRIBBON_BAR_DEFAULT_STYLE );
m_ribbonBar1->SetArtProvider(new wxRibbonAUIArtProvider); 
m_ribbonPage1 = new wxRibbonPage( m_ribbonBar1, wxID_ANY, wxT("File") , wxNullBitmap , 0 );
m_ribbonBar1->SetActivePage( m_ribbonPage1 ); 
m_ribbonPanel1 = new wxRibbonPanel( m_ribbonPage1, wxID_ANY, wxT("File") , wxNullBitmap , wxDefaultPosition, wxDefaultSize, wxRIBBON_PANEL_DEFAULT_STYLE );
m_rbtnBar = new wxRibbonButtonBar( m_ribbonPanel1, wxID_ANY, wxDefaultPosition, wxDefaultSize, 0 );
m_rbtnBar->AddButton( wxID_ANY, wxT("New"), wxNullBitmap, wxEmptyString);
m_rbtnBar->AddButton( wxID_ANY, wxT("Save"), wxNullBitmap, wxEmptyString);
m_rbtnBar->AddButton( wxID_ANY, wxT("Load"), wxNullBitmap, wxEmptyString);
m_ribbonPage2 = new wxRibbonPage( m_ribbonBar1, wxID_ANY, wxT("View") , wxNullBitmap , 0 );
m_ribbonBar1->SetActivePage( m_ribbonPage2 ); 
m_ribbonPanel21 = new wxRibbonPanel( m_ribbonPage2, wxID_ANY, wxT("View") , wxNullBitmap , wxDefaultPosition, wxDefaultSize, wxRIBBON_PANEL_DEFAULT_STYLE );
m_ribbonButtonBar21 = new wxRibbonButtonBar( m_ribbonPanel21, wxID_ANY, wxDefaultPosition, wxDefaultSize, 0 );
m_ribbonButtonBar21->AddButton( wxID_ANY, wxT("Do something"), wxNullBitmap, wxEmptyString);
m_ribbonButtonBar21->AddButton( wxID_ANY, wxT("Do something else"), wxNullBitmap, wxEmptyString);
m_ribbonBar1->Realize();

bSizer4->Add( m_ribbonBar1, 0, wxEXPAND, 5 );

wxBoxSizer* mainSizer;
mainSizer = new wxBoxSizer( wxVERTICAL );

m_ntbkMain = new wxNotebook( this, wxID_ANY, wxDefaultPosition, wxDefaultSize, 0 );
m_panel1 = new wxPanel( m_ntbkMain, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL );
wxBoxSizer* bSizer6;
bSizer6 = new wxBoxSizer( wxHORIZONTAL );

wxBoxSizer* bSizer7;
bSizer7 = new wxBoxSizer( wxVERTICAL );

m_button11 = new wxButton( m_panel1, wxID_ANY, wxT("MyButton"), wxDefaultPosition, wxDefaultSize, 0 );
bSizer7->Add( m_button11, 0, wxALL, 5 );

m_button12 = new wxButton( m_panel1, wxID_ANY, wxT("MyButton"), wxDefaultPosition, wxDefaultSize, 0 );
bSizer7->Add( m_button12, 0, wxALL, 5 );

m_button13 = new wxButton( m_panel1, wxID_ANY, wxT("MyButton"), wxDefaultPosition, wxDefaultSize, 0 );
bSizer7->Add( m_button13, 0, wxALL, 5 );


bSizer6->Add( bSizer7, 1, wxEXPAND, 5 );


m_panel1->SetSizer( bSizer6 );
m_panel1->Layout();
bSizer6->Fit( m_panel1 );
m_ntbkMain->AddPage( m_panel1, wxT("Tab 1"), true );
m_panel2 = new wxPanel( m_ntbkMain, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL );
m_ntbkMain->AddPage( m_panel2, wxT("a page"), false );
m_panel3 = new wxPanel( m_ntbkMain, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL );
m_ntbkMain->AddPage( m_panel3, wxT("a page"), false );
m_panel4 = new wxPanel( m_ntbkMain, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL );
m_ntbkMain->AddPage( m_panel4, wxT("a page"), false );

mainSizer->Add( m_ntbkMain, 1, wxEXPAND, 5 );


bSizer4->Add( mainSizer, 1, wxEXPAND, 5 );


this->SetSizer( bSizer4 );
this->Layout();

this->Centre( wxBOTH );

这就是我想要实现的目标：

Answer 1

这是wxRibbonBar的正常行为。该空间适用于用户提供的文件菜单，或者在实施wxRibbonBar时曾在MS Office应用程序中使用的圆形图标（请参阅http://www.corsix.org/gsoc/ribbon.html）。

在此空间中提供[现在更常见]“文件”菜单的一种方法是从wxRibbonMSWArtProvider（或其他提供者之一）派生您自己的艺术提供者。您需要覆盖::DrawTabCtrlBackground。

以下是一个简单的例子：

void myArtProvider::DrawTabCtrlBackground(
                        wxDC& dc,
                        wxWindow* WXUNUSED(wnd),
                        const wxRect& rect)
{
    // Draw the background for the whole tab area.
    dc.SetPen(*wxTRANSPARENT_PEN);
    dc.SetBrush(m_tab_ctrl_background_brush);
    dc.DrawRectangle(rect.x, rect.y, rect.width, rect.height);

    // Draw the "File" menu background, unfortunately its static and doesn't change when hovered.
    dc.SetBrush (wxColour(35, 70, 135));
    dc.DrawRectangle (rect.x, rect.y, 60, rect.height);
    dc.SetFont (m_tab_label_font);

    // Centre the "File" text in the available space (alternatively this could use wxDC::DrawLabel).
    dc.SetTextForeground (*wxWHITE);
    int text_height;
    int text_width;
    dc.GetTextExtent ("File", &text_width, &text_height);
    int y = rect.y + ((rect.height - text_height) / 2);

    // Draw the "File" text.
    dc.DrawText("File", rect.x + ((60 - text_width) / 2) + 1, y);
}

然后，您需要将wxRibbonBar wxEVT_LEFT_DOWN事件绑定到处理程序函数，该函数执行您在单击“文件”时要执行的任何操作（即显示弹出菜单或整个新页面，如最新版本的办公室）。

结果是这样的： wxRibbonBar with "File" menu
