Floating nav bar that stops fixed to the top of the page

问题 I am trying to mimic something that I have seen a few different times. There is usually a banner with a nav bar below and when the page is scrolled it moves until it touches the top then stops and stays fixed. I am not completely sure how to accomplish this. I have seen a few different things that just dont work. After looking around I figured out it will work something like this but I can seem to get it to work. I think I am missing some stuff <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0

float number range in php. -0 is float?

扶醉桌前 提交于 2019-12-04 02:40:03
问题 when I'm converting string '-0' in float it returns float type -0 example $x = '-0'; $y = (float)$x; result => float -0 why -0 is float number ? 回答1: The IEEE 754 standard, which is how almost all computer languages implement floating point numbers, has both a +0 and a -0 value. For most operations, +0 and -0 can be used interchangeably. However, operations that error out to infinity, use +0 or -0 to go to +Infinity and -Infinity. Because -0 is a valid floating point number, it makes perfect

Show control inside user control outside the boundaries of its parent

人走茶凉 提交于 2019-12-04 01:15:15
问题 I have a usercontrol that has a textbox and a listbox, and it uses them to provides autocomplete functionality to the users. However, I want the listbox to be drawn outside of the boundaries of the user control so that it doesn't get cutoff when the listbox has to be drawn near the edge of the user control. Any tips on how to do that? Essentially I want a listbox floating outside the boundaries of its container control. The only way I can think off is to pass a reference to an outside listbox

How to create a floating touchable activity that still allows to touch native controls outside of its borders?

允我心安 提交于 2019-12-03 19:15:05
问题 What I am trying to achieve is best explained by the scheme I made with mspaint: I have tried to set FLAG_NOT_TOUCH_MODAL which by the description is supposed to be exactly what I want, but it simply does not work. My activity consumes ALL touch events, even outside its borders. If I set FLAG_NOT_FOCUSABLE then of course the native controls under the activity are touchable, but then the activity is completely not even when touching inside its borders. I have tried setting isFloatingWindow

Controlling the precision of floating point number in matlab

瘦欲@ 提交于 2019-12-02 17:11:17
问题 I am dividing a number, say x=2; y=1/3; z=x*y; I expect z to be 0.66666666666667 i.e. 14 numbers after decimal point and the same for y. Now when I do that I get 0.6667 only. How to expand the answer into exact 14 digit precision? 回答1: If it is just about diplaying the number you can use the sprintf function str = sprintf('%.14f', pi); % print PI with exactly 14 digits after decimal point disp(str); Or fprintf with just one line: fprintf('%.14f', pi); fprintf is for writing to files but

How to convert float into Hours Minutes Seconds?

强颜欢笑 提交于 2019-12-02 08:33:47
I've values in float and I am trying to convert them into Hours:Min:Seconds but I've failed. I've followed the following post: Converting a float to hh:mm format For example I've got a value in float format: time=0.6 result = '{0:02.0f}:{1:02.0f}'.format(*divmod(time * 60, 60)) and it gives me the output: 00:36 But actually it should be like "00:00:36". How do I get this? Divmod function accepts only two parameter hence you get either of the two Divmod() So you can try doing this: time = 0.6 mon, sec = divmod(time, 60) hr, mon = divmod(mon, 60) print "%d:%02d:%02d" % (hr, mon, sec) You're not

extjs 3.3: floating panel

谁说胖子不能爱 提交于 2019-12-02 02:56:59
问题 I am trying to create a floating panel over other pre-created panels, I tried following simple codes, but failed: var testPanel = new Ext.Panel({ id: 'testP', width: 50, height: 100, floating: true, title:'Test' }); testPanel.show(); what else I need to think about? thanks! 回答1: Following needs to be taken care of when using the floating config: 1) Fixed width - which you've done 2) The position must be set explicitly after render (e.g., myPanel.setPosition(100,100); ). You can also set the

Does this union break strict aliasing? What about floating point registers

我是研究僧i 提交于 2019-12-02 02:26:14
问题 union { Uint32 Integer; Float32 Real; } Field; I have to use that union for a little IEEE trick, does that break strict aliasing? GCC is not throwing any warning(tried with GCC 4.5 and 4.6 even with pedantic strict aliasing, but As Far As I Know, GCC is not very good catching strict aliasing rules infringiments (lots of false positives/negatives). Field A; A.Integer = (Value1 & B) || Value2; return A.Real; That's the snippet I'm currently using, it seems working correctly without any warning,
