Dear Support,

I’ve made a CExtResizableDialog with some CExtEdit controls on it. I modally show this dialog from a command item of my SDI based application.

I have some problems with the CExtEdit controls’ painting. Let’s say: one of the controls is in focus and I open another window fullscreen over it. After minimizing this second window, my CExtResizableDialog gets the focus again, the caret is blinking in the edit control, as before, but that control is not white inside, but painted over with the dialog’s background color. Only when I move the mouse over the control (and by that forcing it to repaint), it gets back to normal again. Also, one of the edit controls are multiline and the scrollbar of it gets painted over with the background color the same way as the focused control.

I tried inserting this dialog class into your SimpleGrid sample, but it’s acting the same way there as well.

Here’s the code:

in .h:

class CStrangeEditDlg : public CExtResizableDialog
{
	DECLARE_DYNAMIC(CStrangeEditDlg)

public:
	CStrangeEditDlg(CWnd* pParent = NULL);   // standard constructor
	virtual ~CStrangeEditDlg();

// Dialog Data
	enum { IDD = IDD_STRANGE_EDIT_DLG };

protected:
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
	CExtGroupBox ctrlGroupBox;
	CExtLabel        stcTitle;
	CExtEdit          ctrlTitle;
	CExtLabel        stcUserName;
	CExtEdit          ctrlUserName;
	CExtLabel        stcNotes;
	CExtEdit          ctrlNotes;
};

in .cpp:

CStrangeEditDlg::CStrangeEditDlg(CWnd* pParent)
	: CExtResizableDialog(CStrangeEditDlg::IDD, pParent)
{
}

CStrangeEditDlg::~CStrangeEditDlg()
{
}

void CStrangeEditDlg::DoDataExchange(CDataExchange* pDX)
{
	CExtResizableDialog::DoDataExchange(pDX);
	DDX_Control(pDX, IDC_PF_GROUP_ALL, ctrlGroupBox);
	DDX_Control(pDX, IDC_PF_TITLE_STC, stcTitle);
	DDX_Control(pDX, IDC_PF_TITLE_EDIT, ctrlTitle);
	DDX_Control(pDX, IDC_PF_USERNAME_STC, stcUserName);
	DDX_Control(pDX, IDC_PF_USERNAME_EDIT, ctrlUserName);
	DDX_Control(pDX, IDC_PF_NOTES_STC, stcNotes);
	DDX_Control(pDX, IDC_PF_NOTES_EDIT, ctrlNotes);
}

in .rc:

    PUSHBUTTON      "Cancel",IDCANCEL,134,168,50,14,BS_CENTER
END

I tried removing WS_CLIPCHILDREN and WS_CLIPSIBLINGS styles from the dialog resource, but still no luck.
What am I missing?

Best regards,
Chris.

When everything is fine.
After placing another window over it, it’s ruined.

You should not remove the WS_CLIPSIBLINGS | WS_CLIPCHILDREN window style from your dialog. You should open the IDD_STRANGE_EDIT_DLG dialog and change the tab order of its elements (Ctrl+D). The IDC_PF_GROUP_ALL group box should have the highest order number.

I remembered that tab order is essential when using CExtGroupBox, but I thought it had to have the lowest order number. Sorry, it was my fault.

Best regards:
Chris.
