Change colour, Esc-button problems

[pavelvm5]

Hello, it's me again)

I can't find any functions to change title, focus-button, and background (which is blue in app by default) colours in FDialogs, Fwidget in which I create new Fdialogs and in FApplication. For example, i want to make less contrasting theme Grey-Cyan-White, or smth like this. Can you tell me how to make it, or add this features if they aren't exist.

Can i disable esc-button from closing last fdialog or how to override Fclosing event only on this button.

I think, these one are last questions:)

Widget colors

The fastest and easiest way to change the colors is to activate the dark color theme.

FStartOptions::getInstance().dark_theme = true;

You can also read the chapter on user themes, where I described how to create your own theme.

Escape key in dialogs

The escape key press event can be caught by overwriting the onKeyPress method.

Here is a small example:

#include <final/final.h>

using namespace finalcut;

class myDialog : public FDialog
{
  public:
    explicit myDialog (FWidget* parent = nullptr)
      : FDialog{parent}
    {
      button.addCallback
      (
        "clicked",
        [this] () { close(); }
      );
    }

    void onKeyPress (FKeyEvent* ev) override
    {   
      if ( ! ev->isAccepted() && isEscapeKey(ev->key()) )
      {
        ev->accept();
        // Do nothing...
      }
      else
        FDialog::onKeyPress(ev);
    }

  private:
    void initLayout()
    {
      setText ("Dialog window");
      setGeometry (FPoint{25, 5}, FSize{20, 6});
      button.setGeometry (FPoint{5, 2}, FSize{10, 1});
      FDialog::initLayout();
    }

    FButton button{"&Close", this};
};

int main (int argc, char* argv[])
{
  // Enable dark theme
  FStartOptions::getInstance().dark_theme = true;

  FApplication app(argc, argv);
  FMenuBar menubar{&app};
  FMenuItem exit{"E&xit", &menubar};
  exit.addCallback
  (
    "clicked",
    finalcut::getFApplication(),
    &finalcut::FApplication::cb_exitApp,
    &menubar
  );
  myDialog* dialog = new myDialog(&menubar);
  FWidget::setMainWidget(&menubar);
  dialog->focusFirstChild();
  menubar.show();
  return app.exec();
}
