The em-size of this Font.
The following code example demonstrates how to use the Font constructor and the Size, SizeInPoints, and Unit properties. This example is designed to be used with a Windows Form that contains a ComboBox named ComboBox1
that is populated with the strings "Bigger" and "Smaller". Paste the following code into the form and associate the ComboBox1_SelectedIndexChanged
method with the SelectedIndexChanged event of the ComboBox control.
private:
void ComboBox1_SelectedIndexChanged(System::Object^ sender,
System::EventArgs^ e)
{
// Cast the sender object back to a ComboBox.
ComboBox^ ComboBox1 = (ComboBox^) sender;
// Retrieve the selected item.
String^ selectedString = (String^) ComboBox1->SelectedItem;
// Convert it to lowercase.
selectedString = selectedString->ToLower();
// Declare the current size.
float currentSize;
// If Bigger is selected, get the current size from the
// Size property and increase it. Reset the font to the
// new size, using the current unit.
if (selectedString == "bigger")
{
currentSize = Label1->Font->Size;
currentSize += 2.0F;
Label1->Font =gcnew System::Drawing::Font(Label1->Font->Name,
currentSize, Label1->Font->Style, Label1->Font->Unit);
}
// If Smaller is selected, get the current size, in
// points, and decrease it by 2. Reset the font with
// the new size in points.
if (selectedString == "smaller")
{
currentSize = Label1->Font->Size;
currentSize -= 2.0F;
Label1->Font = gcnew System::Drawing::Font(Label1->Font->Name,
currentSize, Label1->Font->Style);
}
}
private void ComboBox1_SelectedIndexChanged(System.Object sender,
System.EventArgs e)
{
// Cast the sender object back to a ComboBox.
ComboBox ComboBox1 = (ComboBox) sender;
// Retrieve the selected item.
string selectedString = (string) ComboBox1.SelectedItem;
// Convert it to lowercase.
selectedString = selectedString.ToLower();
// Declare the current size.
float currentSize;
// Switch on the selected item.
switch(selectedString)
{
// If Bigger is selected, get the current size from the
// Size property and increase it. Reset the font to the
// new size, using the current unit.
case "bigger":
currentSize = Label1.Font.Size;
currentSize += 2.0F;
Label1.Font = new Font(Label1.Font.Name, currentSize,
Label1.Font.Style, Label1.Font.Unit);
// If Smaller is selected, get the current size, in points,
// and decrease it by 1. Reset the font with the new size
// in points.
break;
case "smaller":
currentSize = Label1.Font.SizeInPoints;
currentSize -= 1;
Label1.Font = new Font(Label1.Font.Name, currentSize,
Label1.Font.Style);
break;
}
}
