How do I add simple child window controls (e.g. a button) to a CWindowImpl?
I've looked at CWindowImpl and CDialogImpl. With CDialogImpl, it appears that you just create a dialog template resource and use it, very simple. I would like to do something similar with CWindowImpl, but there doesn't seem to be a way to do it. Must I add the controls manually and position them programmatically?
Some context on what I'm trying to do: I'm trying to create a plug-in for foobar2000, a Windows audio player. I would like to create a "UI element" plugin, and in the sample code that I've looked at, a "UI element" is created via CWindowImpl. How do I add buttons to this CWindowImpl? I've tried using a CDialogImpl instead, but this gives me a "pop-up" dialog, which is not what I'm looking for.
Thanks very much in advance!
With any window, including CDialogImpl, you can add child controls by creating a new window of control class and specifying your parent window handle as a parent for new control. Additionally, SetParent API is here to re-parent any window.

I'm using raw Win32 and C++ for a project. As I understand it, I am able to superclass Windows controls by retrieving the class information, replacing the procedure, then registering this as a new class and using it when creating a new window. Subclassing is done by replacing the window's procedure after the window is created. The advantage of superclassing is that you are able to process messages before CreateWindow() returns.
I'm looking to see if it's possible to superclass a dialog box created with CreateDialog() because I'd like to use a resource file for the dialog layout. The problem is that I don't know how I would provide my superclass when I create a dialog box. Is it even possible? Any idea how MFC handles this?
If you use an extended dialog box template to create your dialog, you can specify a custom window class as part of the DLGTEMPLATEEX definition.
The dialog manager will create and layout your dialog as normal, and call your window procedure for any dialog messages. You can use the DefDlgProc function to obtain default processing for any dialog messages you don't want to handle yourself.
I was trying to find an example of creating a settings/configuration windows. The settings window is launched by clicking "Options" action in the menu item. I wanted to figure out how to open up a 2nd window from the main window. As well how the new window return the settings information back to main window. Tried to play around with the QDialog or some inherited dialog classes, but those are for limited uses, not for general setting window. Is there any example/documentation about this?

I am practice on splitter window, I reference to this web site,
Creating a Splitter Window in a Dialog Box in Three Easy Steps
when I build it, some thing error I cant solve it, like follow code...
Out of memory creating a splitter pane.
Error: Trying to create object which is not DECLARE_DYNCREATE
or DECLARE_SERIAL: CDialogEx.

the other feature, I want to create a two panel with button and static
and listcontrol item.
thanks guy.
Don't use a dialog base application. Just use the wizard. Create a SDI sample with a CFormView... integrate the splitter window later.
It doesn't make sense to me to create a dialog and to integrate all the CFrameWnd features into a CDialog...
I replaced the CDialog1 with CWnd then solved this problem.
ccc.m_pNewViewClass = RUNTIME_CLASS(CWnd);
m_cSplitter.CreateView(0,0, RUNTIME_CLASS(CWnd),
CSize(100,100), &ccc);
m_cSplitter.CreateView(0,1, RUNTIME_CLASS(CWnd),
CSize(100,100), &ccc);
I have tons of existing code using wxWidgets. The main window is wxDialog. Now I have to add a wxMenuBar to that dialog. But, in order to do it, the window should be derived from wxFrame.
Is it possible to add a wxMenuBar to the wxDialog?
If not, is it possible to convert existing code in a way that main window is derived from wxFrame instead from wxDialog?
It's not possible to add a native menu bar to a wxDialog, however, it is possible to use a non-native menu bar control like wxFlatMenuBar (not included with wxWidgets), and add it to the top of the dialog as if it was just another control. Also note though that besides being a non-native menu bar, you also won't be able to use some wxWidgets API to manage it like wxUpdateUIEvents.
There's at least a couple things you will need to take into consideration when changing a wxDialog to a wxFrame.
First, if your dialog is a modal dialog, you will need to manually set the new frame as modal (using wxWindow::MakeModal()) rather than calling ShowModal().
Second, if you had any event handlers setup for the affirmative (OK/Apply button for example) or escape (Cancel or window close) events, you will likely need to rewrite them to handle changes in window behavior.
I want to make a custom made component (a line chart), that would be used in other applications.
I don't know 2 things:
Where should I use (within component class!) the methods for drawing, like FillRect
or PolyLine? In OnPaint handler that I should define and map it in MESSAGE MAP? Will
it (OnPaint handler) be called from OnPaint handler of the dialog of the application
or where from?
How to connect the component, once it is made, to the test application, which will
for example be dialog based? Where should I instantiate that component? From an
OnCreate method of the MyAppDialog.cpp?
I started coding in MFC few days ago and I'm so confused about it.
Thanks in advance,
Cheers.
Painting the control is handled exactly like it would be if it wasn't a control. Given that you're using MFC, that (at least normally) means you do the drawing in the View class' OnDraw (MFC normally handles OnPaint internally, so you rarely touch it).
Inserting the resulting ActiveX control in the host application will be done like inserting any other ActiveX control. Assuming you're doing your development in Visual Studio, you'll normally do that by opening the dialog, right clicking inside the dialog box, and clicking "Insert ActiveX Control..." in the menu that pops up. Pick your control from the list, and it'll generate a wrapper class for the control and code to create an object of that class as needed. From the viewpoint of the dialog code, it's just there, and you can use it about like any other control.
For create new component in MFC, you must create a class from the window class (CWND),
after that you can have your MessageMap for the component and your methods and also can override CWND::OnDraw method to draw the thing you want.
Before that I suggest you to take a look to device context

Good Luck friend.
