In diesem Video zeige ich, wie einfach es ist, wxSizer zu verschachteln.
Um komplexe GUIs zu entwickeln, ist es unabdingbar, dass man Sizer ineinander verschachteln kann. Damit lassen sich einfach und übersichtlich Formulare entwickeln, die dem Benutzer einen hohen Mehrwert bringen.
Hier ein Screenshot unseres Programms:
Hier der Quelltext:
#include <wx/wx.h>
class MyApp : public wxApp {
public:
bool OnInit();
};
class MyFrame : public wxFrame {
public:
MyFrame();
};
IMPLEMENT_APP(MyApp)
bool MyApp::OnInit() {
auto *myFrame = new MyFrame;
myFrame->Show();
SetTopWindow(myFrame);
return true;
}
MyFrame::MyFrame() : wxFrame(nullptr, wxID_ANY, _("Sizer in Sizers")) {
auto *mainPanel = new wxPanel(this);
auto *mainBoxSizer = new wxBoxSizer(wxHORIZONTAL);
auto *flexGridSizer = new wxFlexGridSizer(2, 5, 5);
flexGridSizer->AddGrowableCol(1);
flexGridSizer->AddGrowableRow(4);
flexGridSizer->Add(new wxStaticText(mainPanel, wxID_ANY, _("Firstname:")), 0, wxALIGN_CENTER_VERTICAL | wxALIGN_RIGHT);
flexGridSizer->Add(new wxTextCtrl(mainPanel, wxID_ANY), 0, wxEXPAND);
flexGridSizer->Add(new wxStaticText(mainPanel, wxID_ANY, _("Lastname:")), 0, wxALIGN_CENTER_VERTICAL | wxALIGN_RIGHT);
flexGridSizer->Add(new wxTextCtrl(mainPanel, wxID_ANY), 0, wxEXPAND);
flexGridSizer->Add(new wxStaticText(mainPanel, wxID_ANY, _("Zipcode/City:")), 0, wxALIGN_CENTER_VERTICAL | wxALIGN_RIGHT);
auto *addressSizer = new wxBoxSizer(wxHORIZONTAL);
addressSizer->Add(new wxTextCtrl(mainPanel, wxID_ANY));
addressSizer->AddSpacer(5);
addressSizer->Add(new wxTextCtrl(mainPanel, wxID_ANY), 1);
flexGridSizer->Add(addressSizer, 0, wxEXPAND);
flexGridSizer->Add(new wxStaticText(mainPanel, wxID_ANY, _("Age:")), 0, wxALIGN_CENTER_VERTICAL | wxALIGN_RIGHT);
flexGridSizer->Add(new wxTextCtrl(mainPanel, wxID_ANY));
flexGridSizer->Add(new wxStaticText(mainPanel, wxID_ANY, _("Informations:")));
flexGridSizer->Add(new wxTextCtrl(mainPanel, wxID_ANY), 0, wxEXPAND);
mainBoxSizer->Add(flexGridSizer, 1, wxEXPAND | wxALL, 15);
mainPanel->SetSizer(mainBoxSizer);
mainBoxSizer->SetSizeHints(this);
}
