JTabBar

Menús y navegación · jdashboardUI · B4J / JavaFX

JTabBar crea una navegación horizontal animada con opciones de texto, imágenes o iconos. Puede crearse desde el Designer o con AddToParent.

La imagen mostrada aquí es una referencia visual creada para la documentación y no una captura pixel-perfect.

Ejemplo básico

JTabBar1.AddOptions(Array As String("Home", "Files", "Settings"))
JTabBar1.Show
JTabBar1.Active = 0

Visible y Enabled

La versión actual expone directamente estas propiedades:

JTabBar1.Visible = False
JTabBar1.Visible = True

JTabBar1.Enabled = False
JTabBar1.Enabled = True

Cuando Enabled = False o Visible = False, el control no procesa clics ni dispara el evento de selección. Ya no es necesario acceder manualmente a mBase.

Opciones con imagen o icono

JTabBar1.AddTextWithImage("Files", File.DirAssets, "folder.png", "Files")
JTabBar1.AddTextWithIcon("Settings", Chr(0xE8B8), xui.Color_Blue, xui.CreateMaterialIcons(18), "Settings")
JTabBar1.Show

Evento

Private Sub JTabBar1_itemClicked(Text As String, Index As Int)
    Log(Text & " / " & Index)
End Sub
