B4J Library [B4A] [XUI] SD: XUI_DragView

This library handles drag and drop of XUI views.
It is a simple library with few methods but it only serves to drag the space already indicated.

Good fun

But if You click on the label (just click not drag) nothing happens? In my case view (which is dragable) just dissapear after mouse click. I used your sample.

Hi Peter,
simply because it is more required on mobile devices to drag with your finger.
For Desktop, drag and drop exists in many libraries and was not required of me. I personally don't use it for my apps

Ops. I was wrong. There is no reason, but I have few requests for B4i and therefore I work less on it

Hi there... is it possible for example drag a control (textbox,button) anywhere to a form not at specific placeholder ?

Thanks in advance for your answer

Ho,
In this library no. But you can do it with the SD_XuiView library, you can turn on panel navigation, so you can drag anywhere

Hi Star-Dust, apologies for a rookie question. I try to run your XUI_DragDrop code. I've downloaded "jSD_XUI_DragView 0.02" library to "AdditionalLibraries\B4J" folder, pointed the Additional Libraries path (in Tools - Configure Paths) to "C:\AdditionalLibraries". I got a compilation error (Dim DD As DragDropView: Unknown type: dragdropview). The "jSD_XUI_DragView 0.02" library does not seem to be imported. I don't see it listed in "Libraries Manager". Can you point out what I did wrong? Thanks!

Hi...

is there any "event" when i just drag beforce placed anywhere ?

For example if you have 1 player that is good only for attack - when i drag i want to show only placeholder or placeholders for attack...

because DD_PlacedView / returns values when only placed/dropped...

I don't know if I understand correctly. But you would like some views to be able to position only certain places, while other views may be able to position themselves to other places. And not on any place
