hop of those help? Hi all, , Try this code:
currentDegree=60;
speedDisplayTxt.addTextChangedListener(new TextWatcher()
    {

        public void onTextChanged(CharSequence arg0, int arg1, int arg2,
                int arg3) {
            fromDegrees= currentDegree;
            String speed=txt.getText().toString();
            toDegree= //convert speed to angle here.
            RotateAnimation NeedleDeflection = new RotateAnimation(fromDegrees, toDegrees, ...){
            protected void applyTransformation(float interpolatedTime,Transformation t) {
                float currentDegree = fromDegrees+(toDegrees-fromDegrees)*interpolatedTime;
                super.applyTransformation(interpolatedTime, t);
                };
            NeedleDeflection.setDuration(duration); 
            NeedleDeflection.setFillAfter(true);
            needle.startAnimation(NeedleDeflection);

                  }
             }          

    }

  });

how to stabilize the speed of my wx.Gauge


Tag : development , By : Tornike

will be helpful for those in need This gauge runs with a Thread that reads the file. When you have to read a Txt file the gauge goes fast but when you have to read the Docx the gauge slows down worse when you have to read the texts of an image the gauge crashes the GUI. I want to avoid my GUI crashes. If possible stabilize the speed of the gauge.

Do graphs slow down my calculation speed in a large excel file?

hop of those help? Without seeing your workbook this is hard to answer.
Most likely, it is not the charts (is that what you call "graphs") that are slowing down the recalc, but inefficient formulas.
