Change the "Loading..."

Added by Marcel Tella about 14 years ago

Hi! I'm trying to change the "Loading..." message for "Calculating BPT..." or something like this

I've tried.

  Wt::WDefaultLoadingIndicator* loading = new  Wt::WDefaultLoadingIndicator();
  loading->Wt::WLoadingIndicator::setMessage("Calculating...");
  WApplication::setLoadingIndicator(loading);

It compiles, but doesn't link... so.. Could have any missing library?

The log is this...

bpt_creation_web.cpp:(.text+0x1901): undefined reference to `Wt::WLoadingIndicator::setMessage(Wt::WString const&)'

tools/bpt_creation_web/obj/release/bpt_creation_web.o: In function `bpt_creation_web::bpt_creation_web(Wt::WEnvironment const&)':

bpt_creation_web.cpp:(.text+0x24da): undefined reference to `Wt::WLoadingIndicator::setMessage(Wt::WString const&)'

collect2: ld returned 1 exit status

Thank you!

Hey Marcel,

That should read:

loading->setMessage("Calculating...");

You are explicitly trying to call the implementation in WLoadingIndicator, which is however an abstract class.

Your could could actually be replaced by:

loadingIndicator()->setMessage("Calculating...");

(assuming this is a WApplication).
