Using Greek Letters

[timmay3141]

I want to make a dialog box where I can enter values for a three dimentional vector, but I want to be able to enter them in either spherical or cylindrical coordinates. I want to put the Greek letters commonly used for these values (rho, phi, theta) before edit boxes. It should look like this, except use actual Greek letters:
_________
rho = |________|

_________
phi = |________|

_________
theta = |________|

So my question is, how can I get Greek letters into static text? I tryed copying and pasting, but it pasted a question mark instead of the Greek letter.

Have you looked at doing an "owner-drawn" static text? That way you can specify the "symbol" font in it. Also, I think you can specify the font for any object derived from CWnd.

Alright, I've got it making Greek letters. It will display the appropriate Greek letters when I click the radio button to spherical or cylindrical coordinates using this code:

void CCoordsDlg::OnRadioCoords()
{
// Draw the appropriate cylindrical coordinate symbols
CFont fnGreek;
CDC* pDC = GetWindowDC();

fnGreek.CreatePointFont(120, "Math1", pDC);
m_Coord2.SetFont(&fnGreek);

m_Coord1.SetWindowText("r =" // Normal letter r
m_Coord2.SetWindowText("q =" // Greek letter theta
m_Coord3.SetWindowText("z =" // Normal letter z

ReleaseDC(pDC);
}

void CCoordsDlg::OnRadioCoords2()
{
// Draw the appropriate spherical coordinate symbols
CFont fnGreek;

CDC* pDC = GetWindowDC();
fnGreek.CreatePointFont(120, "Math1", pDC);

m_Coord1.SetFont(&fnGreek);
m_Coord2.SetFont(&fnGreek);
m_Coord3.SetFont(&fnGreek);

m_Coord1.SetWindowText("r =" // Greek letter rho
m_Coord2.SetWindowText("f =" // Greek letter phi
m_Coord3.SetWindowText("q =" // Greek letter theta

ReleaseDC(pDC);
}

Now when I do the SetWindowText for m_Coord1 or 3 on the first function, it draws it bigger than normal, but I didn't change the font on it. What do I need to do?

 

[qednick]

Try using GetDC() instead of GetWindowDC(). Also, you may want to try using CreateFont() instead of CreatePointFont().
Finally, is "Math1" a standard font? I would have thought "symbol" would be a better choice as this is usually a system font.

I didn't know that "symbol" was a standard font (I knew there was a symbol font, but I didn't know it was called "symbol&quot. I looked around in Word for fonts that would let me use the letters, and Math1 let me, so I used it. The problem was simpler than what you mentioned: I simply forgot to tell it to use the default font (MS Sans Serif) when I clicked on the first radio button again.

I've got another problem now. Apparently, the OnInitDialog function ignores any call to SetFont. Here's my code:

BOOL CCoordsDlg::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here
CFont fnGreek;
CFont fnNormal;

CDC* pDC = GetDC();

fnGreek.CreatePointFont(100, "Math1", pDC);
fnNormal.CreatePointFont(80, "MS Sans Serif", pDC);

m_Coord1.SetFont(&fnNormal);
m_Coord2.SetFont(&fnGreek);
m_Coord3.SetFont(&fnNormal);

m_Coord1.SetWindowText("r =" // Normal letter r
m_Coord2.SetWindowText("q =" // Greek letter theta
m_Coord3.SetWindowText("z =" // Normal letter z

ReleaseDC(pDC);

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

It sets the text of m_Coord1, 2, and 3 like it should, but the font isn't Math1 like it should be (I don't know exactly what font it is, but the text size is a lot bigger than it should be too). Any ideas?

 

[qednick]

Have you tried adding TRUE as an extra parameter?

[tt]m_Coord1.SetFont(&fnNormal,TRUE);
[/tt]

Other than that, have you checked the validity of the fonts and the return value from SetFont() in your debugger?
