阅读更多关于 How to get the frame of a view inside another view?

问题 I have an UIImageView in the self.view (the main View) and inside it there is a UIButton .

Calculating UILabel Text Size

阅读更多关于 Calculating UILabel Text Size

I am drawing UILabels programmatically. They get their sizes from a database. So I cannot just use sizeToFit . I have already implemented a function that redraws UILabels with a passed ratio. So all I need to find is the text in UILabel from my view that would require the maximum ratio to redraw UILabels . So finally I need to do something like this: double ratio = 1.00; for (UILabel* labels in sec.subviews) { float widthLabel = labels.frame.size.width; float heightLabel = labels.frame.size.height; float heightText = //get the text height here float widthText = //get the text width here if

AWT custom rendering - capture smooth resizes and eliminate resize flicker

阅读更多关于 AWT custom rendering - capture smooth resizes and eliminate resize flicker

问题 I've been looking at this for several months and so far this is the best I have come up with. The structure (render outside of EDT) is not up for debate, as our application operates this way and will not be rewritten. The application has a layout model and a scripting model which are integrated and drive rendering, so the render must be performed outside of the AWT paint model. What I am trying to arrive at is the optimal and reliable way to perform custom rendering. The following SSCCE works

Html code as IFRAME source rather than a URL

阅读更多关于 Html code as IFRAME source rather than a URL

This standard code for an IFRAME, is there a way to replace the src URL with Just html code? so my problem is simple, I have a page it loads an HTML body from MYSQL I want to present that code in a frame so it renders it self independent of the rest of the page and in the confines of that specific bordering. <iframe src="http://example.com" name="test" height="120" width="600">You need a Frames Capable browser to view this content.</iframe> lonesomeday You can do this with a data URL.

How to prevent my site page to be loaded via 3rd party site frame of iFrame

阅读更多关于 How to prevent my site page to be loaded via 3rd party site frame of iFrame

How can I find out that my page is embedded as a frame to other site during page loading? I guess referrer request header can't help me here? Thanks. You cannot check it from the server's side, but you can use javascript to detect it after the page has loaded. Compare top and self , if they're not identical, you are in a frame. Additionally, some modern browsers respect the X-FRAME-OPTIONS header, that can have two values: DENY – prevents the page from being rendered if it is contained in a frame SAMEORIGIN – same as above, unless the page belongs to the same domain as the top-level frameset

Adding label to frame in Tkinter ignores the attributes of frame

阅读更多关于 Adding label to frame in Tkinter ignores the attributes of frame

问题 I have created a frame of fixed size and now i want to add some labels and other widgets on it. But i observed as soon as i add new widget on this frame its attributes are not honored i.e. size and default back ground color set is not honored. from Tkinter import * tk = Tk() page1 = Frame(tk, bg="blue", width=100, height=200) l1 = Label(page1, text='This is label 1') page1.pack() l1.pack() tk.mainloop() So in the above example if i comment out line 4 & 6, then i can see a frame of fixed size

Can I use setFrame and autolayout on the same view?

阅读更多关于 Can I use setFrame and autolayout on the same view?

I want to add padding to all of my buttons, so I subclassed UIButton, and among other changes, I wanted to add a fixed padding by using setFrame method. Everything was working, except for setFrame. I checked around, and I found out that if I uncheck "using AutoLayout" on that view, then I can use setFrame, and it works. Is there a way around this? I really want to use autolayout, because it helps in making the app look nice on both iphone 5 and earlier devices. But I also would like to use setFrame in my subclass, to make my life a litle easier. Summing up, my question is: Can I use autolayout

I have some labels which I want to adjust their height to the text, this is the code I wrote for this now func heightForView(text:String, font:UIFont, width:CGFloat) -> CGFloat{ let label:UILabel = UILabel(frame: CGRectMake(0, 0, width, CGFloat.max)) label.numberOfLines = 0 label.lineBreakMode = NSLineBreakMode.ByWordWrapping label.font = font label.text = text label.sizeToFit() return label.frame.height } EDIT: The issue was not in this piece of code, so my fix is in the question itself. It might still be useful for others! Anorak I've just put this in a playground and it works for me.
