use_wait_cursor() [1/2]

static bool xtd::forms::application::use_wait_cursor ( )

staticnoexcept

Gets whether the wait cursor is used for all open forms of the application.

Returns

true is the wait cursor is used for all open forms; otherwise, false.

Remarks

When this property is set to true, the use_wait_cursor property of all open forms in the application will be set to true. This call will not return until this property has been set on all forms. Use this property when you have a long-running operation, and want to indicate in all application forms that the operation is still processing.

Examples

The following code example demonstrates the use of application use wait cursor property.

#include <xtd/forms/application>
#include <xtd/forms/button>
#include <xtd/forms/form>
#include <xtd/threading/thread>
 
using namespace xtd;
using namespace xtd::forms;
 
class form1 : public form {
public:
  form1() {
    text("Application use wait cursor example");
    
    button1.auto_size(true);
    button1.location({10, 10});
    button1.parent(*this);
    button1.text("Do something...");
    button1.click += [] {
      application::use_wait_cursor(true);
      for (auto count = 0; count < 500; ++count) {
        application::do_events();
        threading::thread::sleep(10_ms); // Simulate work...
      }
      application::use_wait_cursor(false);
    };
  }
  
private:
  button button1;
};
 
auto main() -> int {
  xtd::forms::application::run(form1 {});
}
