Toolbar and back command issues

[pejo...@gmail.com]

Hi!

Yesterday I suddenly got some issues with the toolbar and back command in my app. I guess it has to do with the changes you recently did  to the toolbar api. To describe the problem, just suppose that I have a app (old GUI-builder app) consisting of 2 forms. The problem occurs when I navigate to form2. 

What I want (and had until yesterday) is that the titlearea of form2 just shows a back arrow (on both Android and iOS) and the title of the form.

 

What i got from yesterday and forward is that a hamburger menu automatically appears in form2, plus a back arrow, plus my back arrow.

Before I used this code to add a back arrow (back command) to form2.

@Override

    protected void beforeForm2(Form f) {

        // Back button in title area

        Style s = UIManager.getInstance().getComponentStyle("TitleCommand");

        FontImage icon = FontImage.createMaterial(FontImage.MATERIAL_NAVIGATE_BEFORE, s);

        //f.getToolbar().addCommandToLeftBar("", icon, (e) -> showForm("Main", f.getBackCommand()));

    }

So how do I remove the hamburger menu from form2? 

I tested to use "f.removeAllCommands();" in the beforeForm2 method and that removes the hamburger menu but as soon as I try to add some back command I got two back arrows.

One strange thing is that if I create a new project my old code works as before as long as I only compile it locally. As soon as I send a Android build to the buildserver then the new thing happens.

 

If you are experiencing an issue please mention the full platform your issue applies to:
IDE: NetBeans
Desktop OS: Linux Mint
Simulator

Never mind!

I found the solution from a similar question at stackowerflow.

I had to add the toolbar manually for the form2 like this:

@Override

protected void beforeForm2(Form f) {

    f.setToolbar(new Toolbar()); 

    f.setTitle("Form2"); 

    Style s = UIManager.getInstance().getComponentStyle("TitleCommand");

    FontImage icon = FontImage.createMaterial(FontImage.MATERIAL_NAVIGATE_BEFORE, s);

   f.getToolbar().addCommandToLeftBar("", icon, (e) -> showForm("Main", f.getBackCommand())); 

}

Does'nt "Toolbar.setGlobalToolbar(true);" work anymore?

There is a regression there which we've fixed already. It will be in this Friday release.

Ok great! I'll wait for that fix then. 

I noticed that the android hardware back-button does'n work with the solution that I tried.

Did you override the setBackCommand method?

Ok I have fixed the override and now it's working, thanks! 

Here is the code if anyone else is looking for the same solution.

// Added this to the statemachine class

 @Override

    protected void setBackCommand(Form f, Command backCommand) {    // added this override 20160526 to fix bug in navigation

        if(shouldAddBackCommandToMenu()) {

            f.addCommand(backCommand, f.getCommandCount());

        }

        f.setBackCommand(backCommand);

    }

// And this is what I have in Form2's before method

  @Override

    protected void beforeForm2(Form f) {

        

        f.removeAllCommands();            

        

        // Back button in title area

        Style s = UIManager.getInstance().getComponentStyle("TitleCommand");

        FontImage icon = FontImage.createMaterial(FontImage.MATERIAL_NAVIGATE_BEFORE, s);

        f.getToolbar().addCommandToLeftBar("", icon, (e) -> showForm("Main", f.getBackCommand()));

    

    }
