OVERVIEW<\/strong><\/p>\n\n\n\n

We take a look at placing controls in a window with absolute positioning. This is not of much practical use except if you make GUI which are of fixed sizes. In the example below, the controls will not change in size and position if you resize the window.<\/p>\n\n\n\n

SAMPLE CODE<\/strong><\/p>\n\n\n\n

absolute.h<\/pre>\n\n\n
\n#include <wx\/wxprec.h>\n#ifndef WX_PRECOMP\n    #include <wx\/wx.h>\n#endif\n\nclass Absolute: public wxFrame {\n\n    public:\n      Absolute(const wxString &title);\n \n};\n<\/pre><\/div>\n\n\n
absolute.cpp<\/pre>\n\n\n
\n#include "absolute.h"\n\n\nAbsolute::Absolute(const wxString &amp;title):\n\n    wxFrame(NULL, -1, title, wxDefaultPosition, wxSize(500,350)) {\n \n    wxPanel *panel = new wxPanel(this, -1);     \n    wxButton *btn = new wxButton(panel, -1, wxT("I am at 20,20"), wxPoint(20,20));\n    wxStaticText *label = new wxStaticText(panel, -1, wxT("I am at 40,100"), wxPoint(40,100));\n\n    wxTextCtrl *edit = new wxTextCtrl(panel, -1, wxT("This is first line\\nThis is second line"),\n\t\t    \twxPoint(100,150), wxSize(220,40), wxTE_MULTILINE);\n\n    Center();\n\n}\n<\/pre><\/div>\n\n\n
main.h<\/pre>\n\n\n
\n#include &lt;wx\/wxprec.h>\n#ifndef WX_PRECOMP\n    #include &lt;wx\/wx.h>\n#endif\n\nclass Main: public wxApp {\n\n\tpublic:\n\t        virtual bool OnInit();\n};\n<\/pre><\/div>\n\n\n
main.cpp<\/pre>\n\n\n
\n#include "main.h"\n#include "absolute.h"\n \nIMPLEMENT_APP(Main)\n\nbool Main::OnInit() {\n\n    Absolute *app = new Absolute(wxT("Absolute Positioning"));\n    app->Show(true);\n}\n<\/pre><\/div>\n\n\n
The output is shown below<\/p>\n\n\n\n
