B4J Question XUI_Touch event: how to consume it after processing ?

[peacemaker]

Hi, All

Is it possible to consume this event cross-platformly after processing ?
When processing is finished - it needs to prevent passing it to the container(-s).

To understand what I mean,

I suggest you create a pane (view) and inside this pane (will be the canvas of your design) create the two items you want... all these into the xuiviewscrollview2d

2) At your example the difference of top,left of one object with other top,left object changing with the move/jumping of scrollview (without dragging the items/objects) ?

I do nothing with ScrollView, manipulating only by the objects created from classes.

create a pane (view) and inside this pane

It's not the first version
Initial work was, sure, without ScrollView, over just Pane - and all worked fully OK, without any jumping.
But the Editor - it's big area for creating many objects, and all must be accesible via small window of the Editor's ScrollView - what is another way ?

2... ok the difference of top,left of one object with other top,left -- is there diffence at the distance when just zoom or using scollbars ?

Spoiler: Examples:

 

[Magma]

not answered my question /// after the jumping of objects - is there any difference between the two objects at top,left ? or still have the same distance ?

 

[peacemaker]

two objects at top,left ? or still have the same distance ?

No coordinates difference, objects are placed into the same one container Pane

 

[Magma]

the container pane name is ?

 

[peacemaker]

Editor.Panel

 

[Magma]

editor.panel is the xuiscrollview2d ? right ?

 

[peacemaker]

Yes

 

[Magma]

So... can you create a new panel (that will include all the objects) ? into the scrollview ?

 

[peacemaker]

Seems, i've already tried, and moved back.
Will try now again

tried:

 

[Magma]

When create the pane (your designer canvas)

create code for when clicking/dragging:
1. at first click take a snap of editor.panelwidth at one variable and the editor.panelheight at other...
2. set editor (xuiscrollview2d) at panelwidth and and height at formheight / widths - the difference dips (titilebar, top from view, vertical scrollbar width, etc)
3. move without jumping
4. when user not clicking/dragging - set again the right values for panelwidth/height

Tell me about the result...

2. set editor (xuiscrollview2d) at panelwidth and and height at formheight / widths - the difference dips (titilebar, top from view, vertical scrollbar width, etc)

Pardon, i did not understand meaning here.

Editor.PanelWidth, Editor.Height - are not changed now during work.

 

[Magma]

    Editor.PanelWidth = B4XPages.GetNativeParent(Me).RootPane.width-15dip '~scrollbar width
    Editor.PanelHeight = B4XPages.GetNativeParent(Me).RootPane.Height-55dip 'is ~titlebar caption height + difference from top

 

[peacemaker]

Sorry, i do not understand.
Yes, while no auto-scrolling - no coordinate jumping.

 

[peacemaker]

How to make the separate topic about "XUI_Touch event: how to consume it after processing ?"

 

[Magma]

Sorry, i do not understand.
Yes, while no auto-scrolling - no coordinate jumping.

I will check... need some hours

 

[Magma]

...Not ready... having problems too

but... try to unzoom (make it smaller) to understand the problem

1. Don't know if that the right way to scale....
2. You are using DesignerCreateView... if you use addview, and createpanel, loadlayout... maybe you can consume mouseevents...

Editor.panel when it is at scale 1 seems that can controlled... So something happens with scaling and scroll....
If you unzoom perhaps 0.1 scale and move object you will more jumping especially when go down... to up not so much...

May you must try different approach at scaling or if you use addview and mousepress, event have better results...

For now ... cant think more... was a break for our IRS... EFT-POS<>ERP connections...

 

[peacemaker]

try different approach

Trying to go ... without a scrollview
