Re: [MSEide-MSEgui-talk] About MSE TSlider.
> or better Huh, to not loose the last position in the tlabel ? Yes, but it is done just after button is released by the audio thread. But ok, it is better ;-) Now the test: Perfect, smooth, direct, no delay, no "scratch". So, this works perfectly: - audio thread event to TSlider: if not TrackBar.clicked then .value:= sender.value; - user event using TSlider: .value:= sender.value; if akind = sbe_thumbposition then := sender.value; Many thanks Martin.

Re: [MSEide-MSEgui-talk] About MSE TSlider.
> >Sorry, I still do not catch ;-( > And I don^t understand what you want to achieve OK, we are both then. :-). Imagine that a song is playing. So the audio thread sent, at each reading of the buffer, some data to the main thread, like position in the sound. Then there is a synchro: the button slider is set at the position given by the audio thread. If I change the position manually while the song is playing, now, the position is changed everytime while moving the slider-button. It is not what I want, I would prefer that the position change only when I release the button, and when the button is not released, only calculate the "virtual position" and give it in the label-position.. (and it is why I did a "custom" TSlider with some public mouse-event that you did not like). I hope you did understand.

And ainfo.eventkind = ek_buttonrelease, what Tslider event gives ainfo data? Thanks.

Set it to false if you don't accept the value. Right button click is normally used to show a popup menu. It is possible to "preview" all mouse messages by tform.onchildmouseevent, check for " (sender = ) and (ainfo.eventkind = ek_buttonrelease) and (ainfo.button = mb_right); " Martin -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ mseide-msegui-talk mailing list mseide-msegui-talk@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mseide-msegui-talk
