I am writing a Form application using Borland C++Builder 6.0. I have put 2 TImage
controls and I have generated the OnClick
event handler as shown below:
void __fastcall TForm1::Image1Click(TObject *Sender)
{
AnsiString imageName;
TImage *image;
// How can I get the image name via the *Sender ?
// How can I convert *Sender into TImage
image = (TComponent)*Sender;
imageName = image->Name;
}
I have assigned the same OnClick
event on both of my TImage
controls.
What I want to achieve is to have one event handler that reads the Name
of the TImage
which is clicked.
As far as I know, this can be done through the TObject *Sender
parameter, but I cannot understand how I can convert the Sender
into a TImage
.
You are on the right track that a simple type-cast will suffice, but your syntax is wrong. Try this instead:
void __fastcall TForm1::Image1Click(TObject *Sender)
{
TImage *image = (TImage*)Sender;
// alternatively:
// TImage *image = static_cast<TImage*>(Sender);
AnsiString imageName = image->Name;
}
