The following example creates a
StringFormat object, sets the string's line alignment, and then gets the line alignment setting and stores it in a variable. The code then creates a second
StringFormat object and uses the stored alignment value to set the line alignment of the second
StringFormat object. Next, the code uses the second
StringFormat object to draw a formatted string. The code also draws the string's layout rectangle.
C++
VOID Example_GetLineAlignment(HDC hdc)
{
Graphics graphics(hdc);
SolidBrush solidBrush(Color(255, 255, 0, 0));
FontFamily fontFamily(L"Times New Roman");
Font font(&fontFamily, 24, FontStyleRegular, UnitPixel);
// Create a StringFormat object, and set its line alignment.
StringFormat stringFormat;
stringFormat.SetLineAlignment(StringAlignmentCenter);
// Get the line alignment setting from the StringFormat object.
StringAlignment stringAlignment = stringFormat.GetLineAlignment();
// Create a second StringFormat object with the same line alignment.
StringFormat stringFormat2;
stringFormat2.SetLineAlignment(stringAlignment);
// Use the second StringFormat object in a call to DrawString.
graphics.DrawString(
L"This text was formatted by a second StringFormat object.",
56, // string length

RectF(30, 30, 150, 200),

// Draw the rectangle that encloses the text.
Pen pen(Color(255, 255, 0, 0));
