touchscreen

问题 So, quite recently I've been working on a website that was given me to improve and make responsive, and one of the issues that I've been faced with is that there are many elements that are clickable, with a mixture of CSS and jQuery effects for hover states. Now, firstly I'd prefer all of these hover states to be CSS, but the main issue I'm having is that on these hover states, certain elements are changing display and visibility css properties. I did some reading, and apparently if this is

问题 In Unity I can't control the touchscreen keyboard. TouchScreenKeyboard class has only one parameters for Android. if(TouchScreenKeyboard.visible) { float keyboardHeight = TouchScreenKeyboard.area.height; // will resize the view here! But this return zero! } Is there any other way to know the height of the keyboard on Android ? 回答1: This should do the trick (found here): public int GetKeyboardSize() { using(AndroidJavaClass UnityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {

问题 I'm working on a painting application for Android and I'd like to use raw data from the device's touch screen to adjust the user's paint brush as they draw. I've seen other apps for Android (iSteam, for example) where the size of the brush is based on the size of your fingerprint on the screen. As far as painting apps go, that would be a huge feature. Is there a way to get this data? I've googled for quite a while, but I haven't found any source demonstrating it. I know it's possible, because

问题 I have Windows 7 with touchscreen attached. My standard Windows Forms Application has several standard buttons. My problem: buttons on form do not show reaction when I click on them using my finger. My form shows that there has been a click on the button but button itself does not react.

Same thing with any standard application like calc.exe 回答1: I performed several experiments and now I believe problem with

问题 Im using a custom touchscreen and I want to activate by default the touch event in node-webkit, is that possible? This one tell node-webkit how to open the app and control how the browser behaves. Update: I'm using Ubuntu like OS, all functionality of touch events work like you are using a mouse(For example you need to scroll down with the scroll bar..).

问题 I have a raspberry pi with a touchscreen running raspbian, I'm hoping to have a Gui on the touchscreen that had a number keypad that when a correct input is entered a pin will output to a door latch or something. I have been over to make a Gui with a number on (by Python) it but i cant get several numbers to sit next to each other. any info will help on this thanks :) This is the code I used to try and place the buttons (you can see i just used a simple LED on/off button Gui and used it to

问题 I am facing an issue with the input into pygame using the following hardware: Raspberry Pi 1 B Adafruit 5" Touchscreen connected via HDMI and Touch Input via USB the Touchscreen is set up according to the howto on the adafruit website (fixing resolution in /boot/config.txt to 800x480px).

问题 Have you ever heard about an accepted paradigm about how to design those kind of systems? Im not talking about iphones but photo-kiosk or manufacturing systems 回答1: Rulas, i have worked on a number of touchscreen apps. i never found a published set of standards like the ones you mention but here is a little bit of what i learned: Create a limited "visual vocabulary" with the following rules: Buttons should be 30 or more pixels high (and at least as wide) - simply increasing the width of a

问题 I'm adapting a Gingerbread kernel for my custom board. I'm trying to replace a resistive touch screen that uses an on-chip ADC controller (S5PV210 processor from Samsung). In my design, I need a capacitive controller supported by eGalaxyTouch driver. It's connected to the USB. The driver can be easily enabled from the "make xconfig" menu. It somewhat works since I added some traces on the serial console and I can see it installing during the kernel boot and I see it install and uninstall

问题 I need to write a script to detect if the physical touchscreen is connected to my Android device at boot time. I tried to list the content of the folder /dev/input via adb and I obtain the following output: root@q88:/dev/input # ls event0 event1 event2 event3 event4 mice If I am not mistaken, event0 identifies the touchscreen, but it is visible in both case the touchscreen is connected or not. Is there a way to detect if the touchscreen is connected to the device? Thanks in advance. 回答1: You
