Android Question Study : How to code the custom view

Theera · Tuesday at 7:36 AM

Hi all,
I have problem about creating the custom view. I've tried to add some code in the expert's code for learning
,but I can't make it completely.

B4X:

'Study
#DesignerProperty: Key: Enabled, DisplayName: Enabled,FieldType: Boolean,DefaultValue:True,Description: Enabled the progressBar
#DesignerProperty: Key: Visibled, DisplayName:Visibled,FieldType: Boolean,DefaultValue:True,Description: Visibled the progressBar

B4X:

Public Sub SetEnabled(myenabled As Boolean)  'Theera's code for study
    Enabled =myenabled
    mBase.Enabled=Enabled
End Sub

Public Sub SetVisibled(myvisibled As Boolean) 'Theera's code for study
    Visibled=myvisibled
    mBase.Visibled=Visibled
End Sub

B4X:

    Private m_Enabled As Boolean = True
    Private m_Visible As Boolean = True

B4X:

Public Sub setEnabled(Enabled As Boolean)  'Theera's code for study
    m_Enabled = Enabled
    mBase.Enabled=Enabled
End Sub

Public Sub setVisible(Visible As Boolean) 'Theera's code for study
    m_Visible = Visible
    mBase.Visible=Visible
End Sub

B4X:

    sel.Enabled = False
    sel.Visible = False

Property Sub (set and get) names must start with lower case letter

Public Sub setEnabled
Public Sub setVisibled

the properties enable and visible are booleans, so the expect either True or False

the lastest, the compiler told me. I never declare enabled and visibled,there are not members . I think I'm lost myself how to code these properties.
I tried to copy the same code,how to do,but it isn't worked.

I think this code has something be wrong.

B4X:

'Study
#DesignerProperty: Key: Enabled, DisplayName: Enabled,FieldType: Boolean,DefaultValue:True,Description: Enabled the progressBar
#DesignerProperty: Key: Visible, DisplayName:Visible,FieldType: Boolean,DefaultValue:True,Description: Visible the progressBar

No, you just don't know how to call them up correctly. Go to the DesignerCreateView sub and do this:

B4X:

    m_Enabled = Props.GetDefault("Enabled",True)
    m_Visible = Props.GetDefault("Visible ",True)

But I recommend that you read the booklet, everything is explained there.

After to compile b4xlib file. It's error message.

Undeclared variable 'enabled' is used before it was assigned any value.

How do I do? ,Sir

Alexander Stolte · Tuesday at 10:51 AM

i don't have any code from you, i don't know how you implemented the things i gave you. Post your class.

Theera · Tuesday at 11:12 AM

Due to the AmirMK82's b4xlib, I have to ask him permit me before, Could I send you privately?

Alexander Stolte · Tuesday at 11:17 AM

if it is a paid library or the license is restricted, you should not send it to me privately. Ask the developer of the original library for help.
