B4J Question Unload imageview

[ThRuST]

Like the headline says, how to unload an imageview from memory after it's been initialized?

This only removes the image, but the object is still allocated in memory (isInitialized true)

ImageView1.RemoveNodeFromParent

 

[XbNnX_507]

ImageView1.Bitmap = Null

 

[ThRuST]

@XbNnX_507 Really? I mast try this. Thank Jo

 

[ThRuST]

In this case, how about

ImageView1.SetImage (Null)

?

 

[ThRuST]

@XbNnX_507 How do you access Bitmap from Imageview? Please privide an example

How do you access Bitmap from Imageview? Please privide an example

 Dim yourImage as Image=   ImageView1.GetImage

 

[ThRuST]

ImageView1.Bitmap = Null

@XbNnX_507 Do you mind provide a complete example because I'm all confused now

 

[XbNnX_507]

ImageView1.Bitmap = null   ' B4A Syntax

ImageView1.setImage( Null ) ' B4J syntax

My Bad.

 

[ThRuST]

Well, I suspected it but I didn't want to make you feel sorry you made a misstake, but it was good we sorted this out.
I was convinced that you knew I was asking about B4J, so this answer is specific for that. Anyway, I checked isInitialized and it says true
so I am not sure you understood my headline. It's one thing to have the image removed, but the object instance seems to be still active.
I guess the old BASIC command ReDim will tell you what I mean. So now when we know how to clear image data we should successfully UNLOAD the object.
Anyone?

 

[ThRuST]

Something like

ImageView1.Close

so there must be a way to unload each of the controls that is initialized, right?

 

[XbNnX_507]

ImageView1.SetImage( Null ) ' <- Just to clear the image reference from the view.
ImageView1.RemoveNodeFromParent ' Remove from the UI 
ImageView1 = Null '<- remove reference 
Log ( ImageView1.isInitialized )  ' <- False

 

[ThRuST]

@XbNnX_507 Nice, now we're talking and do you have the solution for B4A and B4i as well while you're owning the dance floor?

B4XView.RemoveViewFromParent removes a view in the three platforms. In most cases this is the only thing that you need to do to release a view.
