DownNumGlyphs and UpNumGlyphs (C++)

Description

This example shows how to dynamically change the Vcl.Samples.Spin.TSpinButton.DownNumGlyphs and the Vcl.Samples.Spin.TSpinButton.DownGlyph of a Vcl.Samples.Spin.TSpinButton. The same principle is applied for Spin.TSpinButton.UpNumGlyphs and Spin.TSpinButton.UpNumGlyph. To do this example, you need two .bmp files that have drawn on them the 4 states of the button listed in Vcl.Samples.Spin.TSpinButton.DownGlyph. glyphd.bmp is used for the Down button and glyphu.bmp--for the Up button.

Code

class TForm1 : public TForm
{
__published:   // IDE-managed Components
        TImage *Image1;
        TImage *Image2;
        TButton *Button1;
        TSpinEdit *SpinEdit1;
        void __fastcall Button1Click(TObject *Sender);
private:      // User declarations
public:               // User declarations
        __fastcall TForm1(TComponent* Owner);
};

In the .CPP file.

TForm1 *Form1;
 
void __fastcall TForm1::Button1Click(TObject *Sender)
{
                        Graphics::TBitmap *BitmapUp;
Graphics::TBitmap *BitmapDown;
 
BitmapDown =new Graphics::TBitmap();
BitmapUp =new Graphics::TBitmap();
BitmapDown->LoadFromFile("glyphd.bmp");
BitmapUp->LoadFromFile("glyphu.bmp");
 
Form1->Image1->Picture->Bitmap = BitmapUp;
Form1->Image2->Picture->Bitmap = BitmapDown;
 
//Spin button
 
Form1->SpinEdit1->Button->DownGlyph=BitmapDown;
Form1->SpinEdit1->Button->DownNumGlyphs=4;
 
Form1->SpinEdit1->Button->UpGlyph=BitmapUp;
Form1->SpinEdit1->Button->UpNumGlyphs=4;
}
