See the note below UseMenu . You need to call AddFilesToMenu(mnu) only once, right after UseMenu(mnu) -- it is used to populate the menu with files that were put into history before the menu was attached. As for the path not being full... I scanned the source (src/common/docview.cpp) and found that ...

Anyone please correct me if I'm wrong, but I don't think there is a way one could make wxStaticBitmap honour alpha channel (at least not a portable one). I have found a kind of solution that draws the text labels onto the background in the onPaint method and this works, however, I cant do the same t...

I think the problem is not with your custom control itself, it really is in the splitter. But in OBDirCtrl ctor, you're creating a wxGenericDirCtrl as a child of the OBDirCtrl's parent, that is at the same level of widget hierarchy as the wxSplitterWindow is. So what you see in the top-left corner i...

The definition of the array can be found early in treectlg.cpp, just copy it. class WXDLLEXPORT wxGenericTreeItem; WX_DEFINE_EXPORTED_ARRAY_PTR(wxGenericTreeItem *, wxArrayGenericTreeItems); Then I think you'll have to take the whole definition of wxGenericTreeItem class from treectlg.cpp -- you abs...

...unfortunately the GetParent() method returns a wxWindow* and this is not able to convert into a Dlg1* (compiler message) Noone (not even the compiler) should be able to stop you from converting a thing to anything else :P I guess your Dlg1 is a descendant of wxDialog, isn't it? Unlike conversion...

I'm truly sorry :roll: I haven't tested the code I posted. The can't remove file error was caused by the original archive being still open when we tried to replace it with the new one. After realizing this, I was kind of shocked wxFFileInputStream doesn't have a Close() method. Here's a piece of cod...

Is there a way for me to make this work other than having to subclass each child control/window that I dump into the frame and add event handling to each of these controls/windows? Sure. You can connect the frame's handler to the controls. You'll still have to do it for each control, but it's a sin...

What about this? Does it work? The methods are virtual in wxWindow, and I believe wxTextCtrl implements them.

:oops: I guess I was answering a different question. The hook type you need is WH_GETMESSAGE. I also found out that everything I wanted to write about how to connect it is in MSDN under "Using Hooks" -- there are two ways, one through LoadLibrary() and one through linking with the hooking ...

Search this forum for "MSWWindowProc(WXUINT", you'll find a few posts explaining how to handle Windows messages that are not being translated to wxWidgets events. Most of the results are more or less identical copies of this one.

This is from wxMenuXmlHandler::DoCreateResource (src/xrc/xh_menu.cpp): if (m_class == wxT("wxMenu")) { wxMenu *menu = new wxMenu(GetStyle()); wxString title = GetText(wxT("label")); wxString help = GetText(wxT("help")); ... So it constructs a menu without a title. Later...

If you have subclassed wxTreeCtrl, you can just handle EVT_LEFT_DCLICK. If not, you can connect a dummy handler defined in any other window, for example: void MyFrame::onIgnoreMouse(wxMouseEvent& WXUNUSED(event)) { // nothing here, we want that no other handler processes it, // therefore we're n...

Creating custom event types is described in the docs . // in a header where your custom combobox is defined DECLARE_EVENT_TYPE(myEVT_NEED_REFRESH, -1) // in mycombo.cpp DEFINE_EVENT_TYPE(myEVT_NEED_REFRESH) // in the receiving window, you handle it like a wxCommandEvent EVT_COMMAND(myID_COMBO, myEVT...

Yes, this "more iterator-like" functionality of wxTextFile is nonsense, even if we overlook the fact that it's not iterator-like at all because of the last line :) A quick question: what happens if the file is empty? Will wxTextFile contain a single line to prevent this kind of loop from c...

Sure, with the help of wxMemoryFSHandler. You'll have to convert the string into utf-8 (or whatever the value of encoding in the ?xml is) and then add the data to the VFS (virtual file system): // in MyApp::OnInit(), introduce the MemFS to the VFS wxFileSystem::AddHandler(new wxMemoryFSHandler()); /...
