Dear Rooter,
I want to see x-y coordinate from my histogram. I would like to ask if there is any way to show the status bar of a TRootEmbeddedCanvas, for example:
fCanvas->ToggleToolBar();
Thank you,

May be:

Hi,
No, only the canvas itself is embedded. but you can create your own and use signal/slots to display information, as it is done in the TRootBrowser:
TQObject::Connect("TCanvas", "ProcessedEvent(Int_t,Int_t,Int_t,TObject*)",
"TRootBrowser", this,
"EventInfo(Int_t, Int_t, Int_t, TObject*)");
////////////////////////////////////////////////////////////////////////////////
// Set text in culumn col in status bar
void TRootBrowser::SetStatusText(const char* txt, Int_t col)
{
fStatusBar->SetText(txt, col);
}
////////////////////////////////////////////////////////////////////////////////
// Display a tooltip with infos about the primitive below the cursor.
void TRootBrowser::EventInfo(Int_t event, Int_t px, Int_t py, TObject *selected)
{
const Int_t kTMAX=256;
static char atext[kTMAX];
if (selected == 0 || event == kMouseLeave) {
SetStatusText("", 0);
SetStatusText("", 1);
SetStatusText("", 2);
SetStatusText("", 3);
return;
}
SetStatusText(selected->GetTitle(), 0);
SetStatusText(selected->GetName(), 1);
if (event == kKeyPress)
snprintf(atext, kTMAX, "%c", (char) px);
else
snprintf(atext, kTMAX, "%d,%d", px, py);
SetStatusText(atext, 2);
SetStatusText(selected->GetObjectInfo(px,py), 3);
}
Cheers, Bertrand.
