Hi there,
I have been looking through guitest.C to find a way of making a text entry box,
which returns a value when a button is clicked. I have the following script, but
don't know how to attach an action to the button. I notice in guitest.C
->Connect is used for what I assume is the same purpose, but when I try using it
I get an error.
My Script is:
{
TGMainFrame *fMain;
TGCompositeFrame *fStatusFrame;
TGTextEntry *fTestText;
TGButton *fTestButton;
fMain = new TGMainFrame(gClient->GetRoot(), 400, 220);
fStatusFrame = new TGCompositeFrame(fMain, 60, 20, kHorizontalFrame |
kSunkenFrame);
fTestButton = new TGTextButton(fStatusFrame, "&Slice Energy at...", 8);
fStatusFrame->AddFrame(fTestButton, new TGLayoutHints(kLHintsTop |
kLHintsLeft, 2, 0, 2, 2));
fTestText = new TGTextEntry(fStatusFrame, new TGTextBuffer(8));
fTestText->Resize(80, fTestText->GetDefaultHeight());
fStatusFrame->AddFrame(fTestText, new TGLayoutHints(kLHintsTop | kLHintsLeft,
10, 2, 2, 2));
fMain->AddFrame(fStatusFrame, new TGLayoutHints(kLHintsBottom |
kLHintsExpandX,
0, 0, 1, 0));
fMain->SetWindowName("Enter Energy (eV)");
fMain->MapSubwindows();
// we need to use GetDefault...() to initialize the layout algorithm...
fMain->Resize(200,30);
//Resize(400, 200);
fMain->MapWindow();
}
The error when using Connect is:
Error: Can't call
TGTextButton::Connect("Clicked()","TestMainFrame",this,"DoButton()") in current
scope FILE:func.C LINE:488
