How to obtain signal of refresh on the toolbar?


I’m trying to connect the signal emmited when the refresh button of the toolbar of a canvas is cliked, but without success… Thanks in advance to whom is able to helping me.


Hi Jérémie,

There is no simple/direct way of doing this, but you can use this kind of trick:

[code]#include “TCanvas.h”
#include “TGButton.h”
#include “TGToolTip.h”
#include “Riostream.h”

void AnyButtonClicked()
TGButton button = (TGButton)gTQSender;
if (button->WidgetId() == 37) { // refresh
std::cout << "widget ID: " << button->WidgetId() << std::endl;
std::cout << "tooltip text: " << button->GetToolTip()->GetText()->GetString() << std::endl;

void test_toolbar()
TCanvas *c1 = new TCanvas(“c1”, “Simple Canvas”);
if (!c1->GetShowToolBar())
TQObject::Connect(“TGButton”, “Clicked()”, 0, 0, “AnyButtonClicked()”);
Cheers, Bertrand.

It works

Thank you bellenot !!!
