Lockcontrol and zoom

[Rocky]

A small bug which forces some unnecessary flashing...

viewer.lockcontrol=true
viewer.displayfile("xyz.png")
viewer.SetZoom100 'viewer.SetZoomWidthControl
'viewer.redraw 'does not change anything.
viewer.lockcontrol=false

'at this point, the image is not updated might the new zoom !
viewer.redraw 'should not need to add this again, lockcontrol=false should do it ?!
'now it is updated....

Hi Rocky,

Interesting remark !

However, for me the goal of the LockScreen property is to avoid (or not) all refreshing/drawing operations occurring into the viewer.
When you turn this property to False you should not wait for an automatic refresh (this is not the goal of this feature), you have to call the redraw method yourself.

I don't see what you means by "flashing", running your code I haven't this behavior.

Kind regards,

Loïc

Ok, thank you for the explananation about lockcontrol.

Forget about the flashing... it's OK.
