Hi everyone

I wanted to make "autoscrollable panel" - to move it left-right on button click. Form width is 240, panel width 480, I want to show left or right part of it with a nice animation between. It works slow on ppc (refresh of controls takes too long). Any chance to make this move more smooth?

B4X:

For i=-10 To -240 Step -20 
    Panel1.Left=i
    Sleep(50)
    Panel1.Refresh 
 Next
 Panel1.Left=-240

You will have to wait for version 6.0

It's ok for me - now I'm only testing and start more serious programing in next year - then new version should be ready, beacause I see that Erel is by heart involved in developing new versions.

I'm not sure that version 6.0 will help here.
The controls refresh procedure is done by the OS so there is nothing much that can be done in Basic4ppc side.
Why do you need 'Panel1.Refresh' ?

Without Refresh there is no effect of move on my ppc (on desktop it works fine) - just switch between left and right (strange - panel is automatically redrawn after animation and not during it)

You can set the Visible property of some of the controls to false during the movement to make the scrolling smoother.

I personally would go with two timers, one for each directio, assuming just left or right, or 4 if up and down were required!!!....Redraw inside the timer automaticaly refreshes the screen(?)....Th eonly prob I ever encoutered were when usin more than 1 timer simultaneously, the timer ticks are not very accurate!!!
