Spanish [Solucionado] B4J B4XPages Full Screen

[roerGarcia]

Buenos dias, tardes, noches, segun corresponda.

Antes de B4XPages probe crear una aplicacion desktop en modo full screen, habia varias formas de lograr esto, con fx.screen y sus propiedades, con JAVAOBJECT y fijando la forma como maximizada, etc.

Ahora probe uno de esos codigos con B4XPages y salta un error.

Alguien ha probado a crear una app asi? desktop, b4j, b4xpages, full screen?

TIA

Es lo que buscas ??
use;

B4XPages.GetNativeParent

Private fx As JFX

    B4XPages.GetNativeParent(Me).WindowWidth = fx.PrimaryScreen.MaxX - fx.PrimaryScreen.MinX
    B4XPages.GetNativeParent(Me).WindowLeft = fx.PrimaryScreen.MinX
    B4XPages.GetNativeParent(Me).WindowHeight = fx.PrimaryScreen.MaxY - fx.PrimaryScreen.MinY
    B4XPages.GetNativeParent(Me).WindowTop = fx.PrimaryScreen.MinY

B4J:

Dim f As Form = B4XPages.GetNativeParent(Me)

 

[TILogistic]

JavaObject;

Dim Stage As JavaObject = B4XPages.GetNativeParent(Me)
Stage = Stage.GetField("stage")
' Stage.RunMethod("centerOnScreen",Null)
' Stage.RunMethod("setFullScreen",Array As Object(True))
Stage.RunMethod("setMaximized", Array As Object(True))

Revisa este Utilitario si lo haces en JavaObject:

FormUtils

Here are some formutilities that I find useful pretty often. So I put them all in one static class And I thought I'd share it. The most important one, I just found (GetIcons in the lib) allows you to add an icon to display it in the taskbar when the form is minimized (Iconified), I've been...

Un par de detalles.

1. el get native parent retorna un Form. A este se le puede aplicar el fx - dimensiones. Perfecto. Esto funciona. Pero hay un pequeño margen de un par de pixeles no ocupados de la pantalla por la forma de la aplicacion. Solo es una duda existencial.

2. Tambien recuerdo haber retirado los controles de minimizar, maximizar y cerrar del extremo superior derecho con un setformstyle UNDECORATED; aplicar esto mismo al get native arroja este error.

y basicamente esto se corrige usando set form style desde

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
 [B]   MainForm.SetFormStyle("UNDECORATED")[/B]
    MainForm.Show

Ahora nada mas falta agregar los controles de un modo diferente al habitual.

Hasta aqui mi reporte.
Gracias por el apoyo.

Si, OParra, llegamos a la misma situacion ambos dos a la vez. =)

Solo me falto decir antes el deseo de UNDECORAR la forma.

Gracias!

Algo para que tengas presente, ya que para entender mejor este método B4XPages (Clasess).

What is a B4XPage?

It differs between the three platforms:
B4J - Form
B4i - Page in a single NavBarController
B4A - Panel in a single activity.

B4XPages is a library that serves two purposes: 1. Make it simple to develop B4A apps by solving almost all of the challenges involved with Android complex activities life cycle. B4XPages makes B4A behave more similar to B4J and B4i where the new "B4XPage" element is a regular object that is...
