Category :VCL
Platform :All Windows
Product :C++Builder3.x, C++Builder4.x,
Question:
When I perform some fucntionality that
is invoked with a dialog and takes a while to process,
my ToolBar takes a real long time to show the buttons
that are loaded when the dialog disappears.
Answer:
Sounds like a delayed refresh of your ToolBar. To
ensure the ToolBar is immediatley updated make a call to
ToolBar->Repaint() before you compute
but after the Dialog (or similar) is closed.
i.e.
void __fastcall TForm1::Button1Click(TObject *Sender)
{
if (OpenDialog1->Execute())
{
ToolPanel->Repaint();
//load the files, convert, etc...
}
}
