大型机的代码是。

#define _CRT_SECURE_NO_WARNINGS // get rid of warnings preventing compilation
#include "MainFrame.h"
#include <wx/wx.h>
#include "TopicQuestionsFrame.h"
#include "FlashcardsFrame.h"

MainFrame::MainFrame(const wxString& title) : wxFrame(nullptr, wxID_ANY, title) {

    wxPanel* panel = new wxPanel(this);     // creates the panel which the controls will be attached to

    this->SetClientSize(800, 800);
    this->SetMinSize(GetSize());
    this->SetMaxSize(GetSize());

    // image handling

    wxImage::AddHandler(new wxPNGHandler());

    wxBitmap image_bitmap("E:/Coding/Pro 7/Images/backgroundfinal.png", wxBITMAP_TYPE_PNG);
                                                                                                // this tells the program where to fetch the image files
    wxBitmap friends_button_bitmap("E:/Coding/Pro 7/Images/friendstab.png", wxBITMAP_TYPE_PNG);

    wxBitmap classroom_button_bitmap("E:/Coding/Pro 7/Images/classroomtab.png", wxBITMAP_TYPE_PNG);

    this->SetBackgroundColour("#c2cbc6"); // this sets the background colour of the window to the given hex code

    // background and button images

    wxStaticBitmap* background_gui = new wxStaticBitmap(this, wxID_ANY, image_bitmap, wxPoint(0, 0));

    wxBitmapButton* friends_tab = new wxBitmapButton(panel, wxID_ANY, friends_button_bitmap, wxPoint(660, 10), wxSize(102, 92));

    wxBitmapButton* classroom = new wxBitmapButton(panel, wxID_ANY, classroom_button_bitmap, wxPoint(60, 10), wxSize(102, 92));

    // font

    wxFont streak_font(36, wxFONTFAMILY_SWISS, wxFONTSTYLE_NORMAL, wxFONTWEIGHT_BOLD);

    // buttons

    wxButton* topic_questions = new wxButton(panel, wxID_ANY, "Topic Questions", wxPoint(300, 125), wxSize(245, 85));

    wxButton* flashcards = new wxButton(panel, wxID_ANY, "Flashcards", wxPoint(300, 245), wxSize(245, 85));

    wxButton* pop_quiz = new wxButton(panel, wxID_ANY, "Pop Quiz", wxPoint(300, 365), wxSize(245, 85));

    wxButton* customisation = new wxButton(panel, wxID_ANY, "Customisation", wxPoint(300, 485), wxSize(245, 85));

    wxButton* leaderboard = new wxButton(panel, wxID_ANY, "Leaderboard", wxPoint(300, 605), wxSize(245, 85));
    
    // binds

    topic_questions->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 1);  // CreateFrame is called with the current frame, evt and the integer id 1
        });                                         // which allows it to be uniquely identified
                                                    // FrameUtilities:: tells the file where to call the function from.

    flashcards->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 2);      
        });

    pop_quiz->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 2);
        });

    customisation->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 2);
        });

    leaderboard->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 2);
        });

    classroom->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 2);
        });

    friends_tab->Bind(wxEVT_BUTTON, [this](wxCommandEvent& evt) {
        FrameUtilities::CreateFrame(this, evt, 2);
        });

    // text

    wxStaticText* daily_streak = new wxStaticText(this, wxID_ANY, "52", wxPoint(395, 10));

    daily_streak->SetFont(streak_font);

}

这是框架首次加载时的外观。

这是我将鼠标悬停在所有按钮上后的框架的外观。

您不能具有重叠的控件，而

wxBitmapButtons

则与wxStaticBitmap相同，因此您不能将wxStaticBitmap

用于背景图像。而是在面板中绘制位图
