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); } }
