Hello,

 

  • if i make a TUniImage draggable - it works fine in a form 
  • if TUniImage.Parent:=UniScrollBox1; ->  then the draggable TUniImage has sometimes a wrong position  - if the scrollbox-area is scrolled...

 

i made a testcase .. see Posting below

 

ThanX
Erich

i made a TestCase for better understanding ....

 

Info: Please save the "image.png" in uniservermodule.FilesFolderPath

 

 

 

 

if you scroll to the right side - the draggable image has a strange behavior 

 

Info:

I use "uniImage.OnEndDrag   :=   UniPanelMouseEnd;" 

- in this procedure - i recalc the position,   write new position in database and refresh differnt DB-Tables ... a important event for me....

 

 

 

 

Hope - someone can help :-)

 

ThanX

 

Erich

Or you can try to use this approach for now:

//meine_marker[meine_marker_anzahl].Draggable.Enabled:=true;

meine_marker[meine_marker_anzahl].JSInterface.JSAddListener(
                'afterrender',
                'function(me) {'+
                    'Ext.onReady(function() {'+
                        'me.dd=new Ext.dd.DDProxy(me, "");'+
                        'me.constrain=true;'+
                        'me.dd.startDrag=function() {'+                
                            'this.constrainX=true;'+
                            'this.maxX=MainForm.display_image.el.getRight()-me.width;'+
                            'this.minX=MainForm.form.getX();'+
                            'this.constrainY=true;'+
                            'this.maxY=MainForm.display_image.el.getBottom()-me.height;'+
                            'this.minY=MainForm.form.getY();'+
                        '}'+
                    '})'+
                '}'
);

Hello DelphiDeveloper  :-)  Perfect !! ThanX ! :-=

 

 

Just one question .. sorry ;-)
