VTreeView Append Slot

Each item in the treeview can now receive buttons. This is possible due to the "append slot" - which helps append content after each item.



For example here, we have added 4 buttons, these being, add, edit, delete and refresh.

This is possible from the vtreeview abstract designer..



The Generate Members functionality only has 3 events that you can generate for the VTreeView.



Each receiving the item being processed.

As refresh is our own defined menu key, to provide it an event, we just add this code

B4X: 
Private Sub treeName_Refresh (item As Map)
End Sub

VTreeView Append Slot: Hiding Node Buttons.

By default, all the items specified on the Menu Keys will be available for all the items added to the tree. However, one is able to hide/show the buttons per item as per need, as depicted below in the Apps node.



As an example, our menu items are: add; edit; delete; refresh

However we want to hide the edit and delete buttons for the Apps node. We would...

B4X: 
'clear the tree
    trProjects.Clear(page)
    'add a parent node to tree
    trProjects.AddItem("", "apps", "Apps", "", "mdi-semantic-web", False)
    'hide edit/delete for node
    trProjects.SetItemMenuVisible("apps", False, Array("edit", "delete"))
....
....
....
banano.await(trProjects.RefreshWait(page))

VueTable Enhancements

1. Totals Row has a larger font...




2. Compute Totals Can Now also receive field names you want to total without the callback specified. Both methods still work, one with a callback and one without. This is useful when you want to sum a lot of columns.



If a callback is not specified, there is no need for it to be added via code. The formatting applied to this option will be what you specify in "Money" / "Thousands" / "File Size" properties for those fields.

3. To HideColumns at run-time, call

B4X: 
dtQA.HideColumns(Array("col1", "col2", "col3"))

This should also apply to the columns set to be visible in your filter chips

4. To ShowColumns at run-time, call

B4X: 
dtQA.ShowColumns(Array("col1", "col2", "col3"))

This should also apply to the columns set to be visible in your filter chips

5. To change which chips should be "groupable" at runtime, you can call

B4X: 
dtQA.SetGroupAble(Array("col1", "col2", "col3"))

6. To clear the column grouping, call

B4X: 
dtQA.SetGroupBy("")

7. To group by a particular column, call. NB. Only 1 column can be grouped at a time

B4X: 
dtQA.SetGroupBy("col1")

Happy BVAD3 Coding.

BANanoVuetifyAD3 Uses Directives

The BVAD3 library has been updated to include "Uses" directives. These directives tell the library which js and css resources to use.

For example, if you want to use CDN version of vuetify & vue, online fonts etc, you would turn the "Online" directive. When BANano is compiling the library, it will use these directives in AppStart to determine what to add locally or not and BANano.Header.AddJavaScriptFile/BANano.Header.AddCssFile will act accordingly.

Turning Online = True has an effect of you using the online CDN versions of the major css and js files. This is greatly recommended as it affects the speed of your app and the use of caches available on CDN. If however you suspects that your app may be used in areas where internet connectivity is a challenge, make your app a PWA to cache all resources on first run (in an internet available area) or set Online = False.

I have included URLs here as a guide as to what each setting does. Please note that whilst the resources will be included even if set Online is used, they will not be loaded. To avoid this, use the package manager to both "remove" unused js and css file and even source code from the lib.

You can click the links to take you to what that uses directive is about. If you are not using that component, set the directive to False, compile the library and then reference it in your project, rerun it to check if all goes well.

Why you need RemoveDeadCode?

To thin & tree-shake your app, its important that all dead code is removed. Dead code is code that is not used in your app.

Step 1

Comment all subroutine signatures with 'ignoreDeadCode. This is important so that the BANano.Transpiler does not remove used subs. Here is an example

B4X: 
Sub beforeEnter(boTo As Map, boFrom As Map, boNext As BANanoObject)   'ignoreDeadCode

Step 2

in Main > AppStart of your App, this line should exists & uncommented

B4X: 
BANano.TranspilerOptions.RemoveDeadCode = True

Run your app and test of everything is working as expected and if not check the web console log for errors and fix those.

You can also redirect all the B4J logs to an external file and if you want to see which code is marked / will be marked as dead by the BANano Transpiler, also add this line.

B4X: 
BANano.TranspilerOptions.ShowWarningDeadCode =True

To direct the b4j log to an external file, you can use

B4X: 
BANano.TranspilerOptions.RedirectOutput(File.DirApp, "bvadks.log")

Happy BVAD3 coding!

The Date by default is English. One can add date transactions in pgIndex.Init before the AddPages call. This will apply formatting to all pages added to the app


You need to change the Date and Month to have the date-picker show a date specific to your language. Please note this is case SensiTive.

BVAD3 has been updated to fix a few bugs and use the latest version of Vuetify, i.e. 2.6.6. Get your free copy from Github. You will find how to use the FluidMeters as requested by SD from the updated New Awesome Kitchen Sink. Happy BVAD3 coding. PS: There is also one other user request on LeafLet that I hope to sort out soon.

These are featured here:

Liquid Progress Indicator With JavaScript And Canvas - fluid-meter.js | CSS Script

fluid-meter.js is a JavaScript library to create a circular progress indicator with a fluid/water-like effect using Canvas API.

Hi there gang, it is with pleasure to release the first version of the BVAD3 API Documentation. Please check it out, send us your thoughts and feelings. Have fun,

NB: The API depends on a PHP Web Server running, you can get the latest BVAD3 version + Kitchen sink and run a local copy. GitHub + Netlify are for "static" websites, so you might not see the documentation there.
