Add icon to submenu

[daniloz]

Hi All,

I'm trying to add an icon to a submenu added by a plugin to no avail...

Here's what I'm trying to do

Code Select Expand


wxString prefix = ConfigManager::GetDataFolder() + _T("/images/cbvss/");
wxBitmap* bmp = new wxBitmap(cbLoadBitmap(prefix + _T("vss.png"), wxBITMAP_TYPE_PNG));

[... Build menu ...]

wxMenuItem* subMenu =  menu->AppendSubMenu(VssMenu, title, _("Help"));
subMenu->SetBitmap(*bmp);


The file vss.png exists under the prefix dir.

Any help?

This is how DoxyBlocks does it:

Code Select Expand


void DoxyBlocks::BuildMenu(wxMenuBar *menuBar)
{
   //The application is offering its menubar for your plugin,
   //to add any menu items you want...
   //Append any items you need in the menu...
   //NOTE: Be careful in here... The application's menubar is at your disposal.
//    NotImplemented(wxT("DoxyBlocks::BuildMenu()"));

   int idx = menuBar->FindMenu(_("P&lugins"));
   if(idx != wxNOT_FOUND){
       wxMenu *submenu = new wxMenu;
       wxString sDataFolder(ConfigManager::GetDataFolder());
       wxString prefix = sDataFolder + wxT("/images/DoxyBlocks/16x16/");

       wxMenuItem *MenuItemDoxywizard = new wxMenuItem(submenu, ID_MENU_DOXYWIZARD, _("&Doxywizard...\tCtrl-Alt-D"), _("Run doxywizard."));
       MenuItemDoxywizard->SetBitmap(wxBitmap(prefix + wxT("doxywizard.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemDoxywizard);
       wxMenuItem *MenuItemExtract = new wxMenuItem(submenu, ID_MENU_EXTRACTPROJECT, _("&Extract documentation\tCtrl-Alt-E"), _("Extract documentation for the current project."));
       MenuItemExtract->SetBitmap(wxBitmap(prefix + wxT("extract.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemExtract);
       submenu->AppendSeparator();
       wxMenuItem *MenuItemBlockComment = new wxMenuItem(submenu, ID_MENU_BLOCKCOMMENT, _("&Block comment\tCtrl-Alt-B"), _("Insert a comment block at the current line."));
       MenuItemBlockComment->SetBitmap(wxBitmap(prefix + wxT("comment_block.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemBlockComment);
       wxMenuItem *MenuItemLineComment = new wxMenuItem(submenu, ID_MENU_LINECOMMENT, _("&Line comment\tCtrl-Alt-L"), _("Insert a line comment at the current cursor position."));
       MenuItemLineComment->SetBitmap(wxBitmap(prefix + wxT("comment_line.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemLineComment);
       submenu->AppendSeparator();
       wxMenuItem *MenuItemRunHTML = new wxMenuItem(submenu, ID_MENU_RUNHTML, _("Run &HTML\tCtrl-Alt-H"), _("Run HTML documentation."));
       MenuItemRunHTML->SetBitmap(wxBitmap(prefix + wxT("html.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemRunHTML);
       wxMenuItem *MenuItemRunCHM = new wxMenuItem(submenu, ID_MENU_RUNCHM, _("Run &CHM\tCtrl-Alt-C"), _("Insert a comment block at the current line."));
       MenuItemRunCHM->SetBitmap(wxBitmap(prefix + wxT("chm.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemRunCHM);
       submenu->AppendSeparator();
       wxMenuItem *MenuItemConfig = new wxMenuItem(submenu, ID_MENU_CONFIG, _("Open &preferences...\tCtrl-Alt-P"), _("Open DoxyBlocks' preferences."));
       MenuItemConfig->SetBitmap(wxBitmap(prefix + wxT("configure.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemConfig);
       submenu->AppendSeparator();
       wxMenuItem *MenuItemLoadTemplate = new wxMenuItem(submenu, ID_MENU_LOAD_TEMPLATE, _("L&oad settings template"), _("Load saved settings template."));
       MenuItemLoadTemplate->SetBitmap(wxBitmap(sDataFolder + wxT("/images/16x16/fileopen.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemLoadTemplate);
       wxMenuItem *MenuItemSaveTemplate = new wxMenuItem(submenu, ID_MENU_SAVE_TEMPLATE, _("&Save settings template"), _("Save current settings for future use."));
       MenuItemSaveTemplate->SetBitmap(wxBitmap(sDataFolder + wxT("/images/16x16/filesave.png"), wxBITMAP_TYPE_PNG));
       submenu->Append(MenuItemSaveTemplate);

       Connect(ID_MENU_DOXYWIZARD, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::RunDoxywizard);
       Connect(ID_MENU_EXTRACTPROJECT, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::ExtractProject);
       Connect(ID_MENU_BLOCKCOMMENT, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::BlockComment);
       Connect(ID_MENU_LINECOMMENT, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::LineComment);
       Connect(ID_MENU_RUNHTML, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::RunHTML);
       Connect(ID_MENU_RUNCHM, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::RunCHM);
       Connect(ID_MENU_CONFIG, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::Configure);
       Connect(ID_MENU_LOAD_TEMPLATE, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::ReadPrefsTemplate);
       Connect(ID_MENU_SAVE_TEMPLATE, wxEVT_COMMAND_TOOL_CLICKED, (wxObjectEventFunction)&DoxyBlocks::WritePrefsTemplate);

       menuBar->Insert(idx + 1, submenu, wxT("Do&xyBlocks"));
   }
}


You could try:

Code Select Expand


subMenu->SetBitmap(wxBitmap(prefix + wxT("vss.png"), wxBITMAP_TYPE_PNG));


Edit:
I do not believe wxWidgets allows (sub)menus to have icons; see wxMenu Class Reference (as opposed to wxMenuItem's, which do allow icons).

@Alpha thanks for you reply!

I do not believe wxWidgets allows (sub)menus to have icons; see wxMenu Class Reference (as opposed to wxMenuItem's, which do allow icons).

I'm trying to add an icon to a menu item.
And following your post, I tried to add the icon to a menu item in the menu bar and it works, as for the DoxygenPlugin.

However, this is not what I want to do. I want to add an icon to a menu item in the context menu. I tried to do it in exactly the same way, but it's still not working.

Do anyone knows if this is even possible, i.e. to have an icon in a context menu item?

Edit:
Ok, I found the reason, there's a bug report here: http://trac.wxwidgets.org/ticket/3206

"The code from description of this ticket isn't working, because we adding image after append item to menu. It will be work correctly, if we added icon before added/append item to menu."
