SlideRule

SlideRule is a custom UI widget that allows you to have a "slider-like" object that can extend beyond the bounds of your window.

Code Sample

First Example - creates a simple Slide Rule with default parameters.

SlideRuleControlView * slideRuler = [[SlideRuleControlView alloc] initWithFrame:CGRectMake(10, 150, 300, 50)];
CustomSliderTheme * theme = [CustomSliderTheme buildTheme:kCSThemeWhite];
[view addSubview:slideRuler];
[slideRuler applyTheme:theme];
[slideRuler release];	

But more realistically, you might want a label to display the value, set parameters, and of course apply a theme to the sliderule.

SlideRuleControlView * slideRuler = [[SlideRuleControlView alloc] initWithFrame:CGRectMake(10, 150, 300, 50) params:parms];
CustomSliderTheme * theme = [CustomSliderTheme buildTheme:kCSThemeWhite];
[view addSubview:slideRuler];
[slideRuler applyTheme:theme];
	

SlideLabel * label = [[SlideLabel alloc] initWithFrame:CGRectMake(10, 200, 300, 30)];
[view addSubview:label];
[label setTextColor:[UIColor lightGrayColor]];
[slideRuler setSlideDelegate:label];
[label release];

// update our parameters to change the second slide rule
parms->minValue = 100.0f;
parms->maxValue = 400.0f;

SlideRuleControlView * secondSlider = [[SlideRuleControlView alloc] initWithFrame:CGRectMake(10, 300, 300, 50) params:parms];
[view addSubview:secondSlider];
[secondSlider setCurrentValue:150.0];
[secondSlider release];
