OpenCV - getting the slider to update its position during video playback

风格不统一 提交于 2019-11-29 00:54:20
问题 I've picked up 'Learning OpenCV' and have been trying some of the code examples/exercises. In this code snippet, I want to get the slider to update its position with each video frame change, but for some reason it won't work (the picture freezes with the following code): #include "cv.h" #include "highgui.h" int g_slider_position = 0; CvCapture* g_capture = NULL; void onTrackbarSlide(int pos) { cvSetCaptureProperty(g_capture, CV_CAP_PROP_POS_FRAMES, pos); } int main(int argc, char** argv) {

jQuery UI Slider: move the value along (with) the handle

老子叫甜甜 提交于 2019-11-28 21:26:15
问题 I used the jQuery UI slider component in my page to set a range of prices. I can also use their ui.values[] to set and show the new values in other divs. How can I make to see the new value under the handle . I.e. if I moved the handle to $100, I want to set the "$100" text right under that handle. BTW, I use the range version - to set a range of prices, so I got TWO handles on my slider (min & max). var minPriceRange=100; var maxPriceRange=500; $( "#priceRangeSlider" ).slider({ range: true,

How to refresh a jQuery UI Slider after setting min or max values?

二次信任 提交于 2019-11-28 21:12:20
I have a ui.slider and change it's min and max values on runtime. But these changes only get reflected in the view, when I set the values afterwards too (which causes it to fire events that are not needed). In my opinion, it should refresh the view after setting min and max too. Is there a simple workaround, seems like a refresh method is missing for the slider. $("#something").slider({ range: true, values: [25, 75], min: 0, max: 100 }); $("#something").slider("option", "min", 25); // left handle should be at the left end, but it doesn't move $("#something").slider("option", "values", [25, 75]

iOS how to make slider stop at discrete points

限于喜欢 提交于 2019-11-28 17:25:58
I would like to make a slider stop at discrete points that represent integers on a timeline. What's the best way to do this? I don't want any values in between. It would be great if the slider could "snap" to position at each discrete point as well. To make the slider "stick" at specific points, your viewcontroller should, in the valueChanged method linked to from the slider, determine the appropriate rounded from the slider's value and then use setValue: animated: to move the slider to the appropriate place. So, if your slider goes from 0 to 2, and the user changes it to 0.75, you assume this

How to change Jquery UI Slider handle

久未见 提交于 2019-11-28 15:40:31
问题 I want to modify the stock JQuery UI slider so that the handle has a arrow on it rather than being a square. i.e. I want to use a custom image as the handle. There are a few tutorials that do it: http://jqueryfordesigners.com/slider-gallery/ http://www.ryancoughlin.com/2008/11/04/using-the-jquery-ui-slider/ http://www.keepthewebweird.com/creating-a-nice-slider-with-jquery-ui/ But I can't get it to work. The following code results in a stationary handle image: <!DOCTYPE html> <html> <head>

Simple way of creating jQuery Slider

走远了吗. 提交于 2019-11-28 14:53:40
I wanted to create a simple static jQuery based slider. Right now I just have the design. It has small dots as pagination in the right bottom, with a heading, an image and some content. It should be able to loop infinitely and also should have the ability to play and pause. Not much features are required. Today I tried a content slider, with fixed pagination. I implemented this for something, which I would say after it is released. I could have simply used a plug-in, but due to some technical issues, and I too wanted to learn something, so I did it on my onw. I started with the HTML Markup,
