B4J Question How to close page completely

[Nitin Joshi]

There are 2 pages in project "Main Page" and "Run Page". From Main Page, I show "Run Page". When i come back to Main Page, i want Run Page to get close completely. How can i achieve this?

How do you come back to MainPage?
What do you mean by "close completely"?

How do you come back to MainPage?

When I am on RunPage, i can see option to click MainPage.

What do you mean by "close completely"?

Means when i come back to MainPage, RunPage is still open. I want that page to close completely or destroy because when again i open RunPage, buttons on RunPage are new because every time i create button dynamically. some times 12, some times 30 etc....

Please see below screenshot.

I hope, i could convey my request.

You want to clear all the views and reload the layout again?

RunPage:

Sub Class_Globals
    Private Root As B4XView 'ignore
    Private xui As XUI 'ignore
End Sub

Public Sub Initialize As Object
    Return Me
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
End Sub

Private Sub B4XPage_Appear
    Root.LoadLayout("RunPage")
    B4XPages.SetTitle(Me, "Run Page")
End Sub

Private Sub BtnClose_Click
    Root.RemoveAllViews
    B4XPages.ClosePage(Me)
    B4XPages.ShowPage("MainPage")
End Sub

 

[William Lancee]

When the MainPage button is pressed, does Run Page close itself?

B4XPages.ClosePage(Me)

When you get back to MainPage, Run Page should invisible.
If you want to change to content of Run Page next time you show it., use:

Private Sub B4XPage_Appear
  
End Sub

Sorry @aeric I send my response at same time.

Thanks @aeric and @William Lancee , highly appreciate. I will look into both suggestion. However, please allow me to share more with you to elaborate bit better. I am adding 3 pictures. One is Main Page and 2 pictures from Run Page.

Please see picture "Second Time Run Page 24 buttons"...you will see 24 buttons are there however at back side showing earlier 12 buttons.

I hope, you got my point. Can i close or destroy runpage before MainPage appears? or is there any better solution?

Can i close or destroy runpage before MainPage appears? Yes
The important B4XPage_Appear sub is in Run Page not in Mainpage

Check my example first.

By the way, are you creating for B4i? This is B4J forum.

 

[William Lancee]

If "B4i" the MainPage button automatically closes the Run Page, no need to close it yourself.

B4i...By mistake selected B4J forum....Sorry.

I seldom use B4XPage_Appear and B4XPage_Disappear.
Maybe you can also use B4XPage_Disappear.

Private Sub B4XPage_Disappear
    Root.RemoveAllViews
End Sub

Private Sub BtnClose_Click
    'Root.RemoveAllViews
    B4XPages.ClosePage(Me)
    B4XPages.ShowPage("MainPage")
End Sub

• B4XPage_Disappear - Called whenever a visible page disappear.

I checked the example.

Private Sub BtnClose_Click Root.RemoveAllViews B4XPages.ClosePage(Me) B4XPages.ShowPage("MainPage") End Sub

It wont work for me because in RunPage, there is no BtnClose button to close the page.

If i add code in MainPage to close the RunPage then error occurs when first time ShowPage("RunPage") is executed.

Main Page Code...

'This is the code from B4XMainPage
Private Sub B4XPage_Appear()
    B4XPages.ClosePage("RunPage")
End Sub

 

[William Lancee]

The important B4XPage_Appear sub is in RunPage NOT in Mainpage.
That's the place where you redesign the RunPage.
You don't have to close anything, it is also automatic.

The sequence is Mainpage -> RunPage > Mainpage -> RunPage (when RunPage "Appears" BUT before you see it remake/reload your layout.)

Please see picture "Second Time Run Page 24 buttons"...you will see 24 buttons are there however at back side showing earlier 12 buttons.

@William Lancee @aeric , I was loading layout in Page Create event, that was my mistake. I moved to Page Appear event. This issue has been solved.

Thanks for the support.
