I am trying to build a memory game with 16 pairs of cards.
I do not know exactly how to implement an OnClick
event. I am new at using C++Builder, so please help.
The images are in an array, I allocate them dynamically like this:
for(int i=0;i<4;i++)
{
for(int j = 0; j < 8 ; j++)
{
VectorOfImages[i*8+j]=new Card(9+i*112,9+j*112,pan, 0);
VectorOfImages[i*8+j]->image->Picture>LoadFromFile("...OOP\\c\\images\\0.bmp");
VectorOfImages[i*8+j]->image->Tag=i*8+j;
VectorOfImages[i*8+j]->image->Enabled=false;
}
}
OnClick
is a property of TImage
, you can assign it like you would any other property, eg:
for(int i = 0; i < 4; ++i)
{
for(int j = 0; j < 8; ++j)
{
int idx = (i*8) + j;
VectorOfImages[idx] = new Card(9+i*112, 9+j*112, pan, 0);
VectorOfImages[idx]->image->Picture->LoadFromFile("...OOP\\c\\images\\0.bmp");
VectorOfImages[idx]->image->Tag = idx;
VectorOfImages[idx]->image->Enabled = false;
VectorOfImages[idx]->OnClick = &ImageClicked; // <-- here
}
}
Then, add ImageClicked()
to your Form:
private:
void __fastcall ImageClicked(TObject *Sender);
...
void __fastcall TMyForm::ImageClicked(TObject *Sender)
{
// Sender points at the TImage that was clicked...
TImage *Image = static_cast<TImage*>(Sender);
// use Image as needed...
}
