Program of the Week PW5 Page 1 This week the Notepad program will be finished. This week is going to add a 'File Save' option allowing selection of a file to write the wxTextCtrl into a file. The existing wxEditor program (PW4) will be further modified to include a save file dialog according to the following instructions. Modifications to the wxEditor project code. Header file: In wxEditorMain.h is the wxEditorFrame class declaration 1. A declaration for a wxFileDialog pointer has to be added just below the wxTextCtrl pointer declaration: wxFileDialog* saveDialog 2. there is an enum list declaring ID items as follows: enum { idMenuQuit = 1000, ID_TextBox, idMenuOpen, idMenuAbout }; add another ID entry for file save: idMenuSave 3. there is the following list for menu items void OnClose(wxCloseEvent& event); void OnQuit(wxCommandEvent& event); void OnAbout(wxCommandEvent& event); add another item for OnSave command event. Code file: In wxEditorMain.cpp are pieces which constitute the Frame components of the program. 4. There is the event table connecting event ID's to member functions of the wxEditorFrame BEGIN_EVENT_TABLE(wxHelloWorld2Frame, wxFrame) EVT_CLOSE(wxHelloWorld2Frame::OnClose) EVT_MENU(idMenuQuit, wxHelloWorld2Frame::OnQuit) EVT_MENU(idMenuAbout, wxHelloWorld2Frame::OnAbout) EVT_MENU(idMenuOpen, wxHelloWorld2Frame::OnOpen) END_EVENT_TABLE() Add an event table item connecting idMenuSave with OnSave function Program of the Week PW5 Page 2 5. Part of the wxEditorFrame constructor is code to create the menu bar // create a menu bar wxMenuBar* mbar = new wxMenuBar(); wxMenu* fileMenu = new wxMenu(_T("")); fileMenu->Append(idMenuOpen, _("&Open\tAlt-F5"), _("Open a file")); fileMenu->Append(idMenuQuit, _("&Quit\tAlt-F4"), _("Quit the application")); mbar->Append(fileMenu, _("&File")); Add a ‘Save’ fileMenu item to save a file. Append the item 'Save', with explanatory text 'Save a file' connecting the idMenuSave event. 6. Add a member function which actually create a File Dialog instance. 'File Save' code is added to open/load a selected file. void wxHelloWorldFrame::OnSave(wxCommandEvent &event) { } This is the code which will do those 4 items. The intention is that you study these 4 lines of code and develop an understanding of what they are doing. 1. Create an instance of the wxFileDialog wxFileDialog *saveDialog = new wxFileDialog(this, wxT("Choose a file"), wxT(""), wxT(""), wxT("Text Files (*.txt)|*.txt|C++ Files (*.cpp)|*.cpp|Header Files (*.h)|*.h"), wxFD_SAVE ); To get the file save dialog, wxFD_OPEN style is replaced with wxFD_SAVE 2. Cause the instance to 'pop-up' (ShowModal) int response = saveDialog->ShowModal(); //get response from the dialog 3. Check if the response is 'OK'’. Save the wxTextCtrl inside the wxFrame to the selected file if(response == wxID_OK) { //if response ok, then load contents into textControl this->textControl->SaveFile(saveDialog->GetPath()); } Build and run the finished program. Turn in a screen copy with the file save dialog activated and the Application Frame with the Time and Date in the Status Bar See below: Program of the Week PW5 Page 3 Homework 6 Make sure you add the time and date to your work when completed so it can be seen when reviewed Containers: For each of the containers below, give a 2 or 3 sentence description of how it works. Additionally, give an example of the constructors (default and overloaded). There are usually 3 or 4 of these. All the information is available through a reference site like the one below. This includes examples of the constructors as actual code www.cplusplus.com 1. vector 2. list 3. queue 4. stack 5. set 6. map 7. multiset 8. multimap Algorithms For the algorithms below, give a 2 or 3 sentence description of how it works and what the calling arguments are. Give an example of how the algorithm is called 9. find 10. search 11. copy 12. move 13. swap 14. sort 15. max
