Code
void __fastcall TForm1::ButtonTSClick(TObject *Sender)
{
TRect MyRect;
if (myActiveControl == NULL) exit;
MyRect = myActiveControl->BoundsRect;
MyRect.Right = MyRect.Left + (MyRect.Right - MyRect.Left) / 2;
MyRect.Bottom = MyRect.Top + 2 * (MyRect.Bottom - MyRect.Top);
myActiveControl->BoundsRect = MyRect;
}
void __fastcall TForm1::ButtonSFClick(TObject *Sender)
{
TRect MyRect;
if (myActiveControl == NULL) exit;
MyRect = myActiveControl->BoundsRect;
MyRect.Right = MyRect.Left + 2 * (MyRect.Right - MyRect.Left);
MyRect.Bottom = MyRect.Top + (MyRect.Bottom - MyRect.Top) / 2;
myActiveControl->BoundsRect = MyRect;
}
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
TComponent *Temp;
TListItem *ListItem;
ListView1->ViewStyle = vsList;
ListItem = ListView1->Items->Add();
ListItem->Caption = "Components: ";
for (int I = ComponentCount - 1; I >= 0; I--)
{
Temp = Components[I];
ListItem = ListView1->Items->Add();
ListItem->Caption = Temp->Name;
}
}
void __fastcall TForm1::ListView1SelectItem(TObject *Sender, TListItem *Item,
bool Selected)
{
TComponent *comp = FindComponent(Item->Caption);
if (dynamic_cast<TWinControl *>(comp) != NULL)
myActiveControl = dynamic_cast<TWinControl *>(comp);
