问题 react-native Dimensions.get("window").width return 375 for an iPhone 6s.... it seems far from correct. ` import React, { Component } from 'react'; import { AppRegistry, StyleSheet, Text, View, Dimensions } from 'react-native'; class AwesomeProject extends Component { render() { return <Text style={{margin:50}}>Width: {Dimensions.get("window").width}</Text>; } } AppRegistry.registerComponent('AwesomeProject', () => AwesomeProject);` 回答1: 375 is the number of points across for the iPhone 6.

问题 I placed a Panel on my custom page and gave it a width of SurfaceWidth . Then I changed its width to SurfaceWidth div 2 . Here's the result: As you can see from the screenshot the new panel's width is definitely not equal to SurfaceWidth div 2 . Why is that so? Here's the code: [Setup] WizardStyle=modern [Code] procedure InitializeWizard(); var Page: TWizardPage; Panel: TPanel; begin Page := CreateCustomPage(wpWelcome, 'Custom wizard page controls', 'TButton and others'); Panel := TPanel

问题 Well, I have this code: http://jsfiddle.net/hv9gB/3/ (function() { var img = document.getElementById('my_image'); // Original var width, height; // Display var d_width = img.width; var d_height = img.height; var updateDetail = function() { document .getElementById('display_size') .innerHTML = 'Display Size: ' + d_width + ' x ' + d_height; document .getElementById('native_size') .innerHTML = 'Original Size: ' + width + ' x ' + height; }; // Using naturalWidth/Height if (img.naturalWidth) {

问题 I'm trying to take a text string, (e.g. the word "testing") and calculating if the string, when displayed on screen, will exceed a certain width. I do this by putting it in a element and using width(). Now, the thing is I want to reduce the text string by a character at a time, and then determining the width. If the width is within say "130px", then i'll return that truncated string. I have the following recursive function, but I'm quite new to Js/jQuery and am unsure what I did wrong. If the

问题 I want to combine 4 figures in the same plot. Each barplot is related to the image plot. I want the bar width to be exactly the same width as the grid width in the image plot. The up-barplot and the left-barplot. I have pasted my code to follow. How can I modify for this purpose? Or can I use ggplot2 for this? datMat <- matrix(rep(1, 100), nrow=10) op=par(oma=c(1, 1, 1, 1), mar=c(1, 1, 1, 1), lwd=0.2, cex=.5) nf <- layout(matrix(c(0, 1, 0, 2, 3, 4), 2, 3, byrow=TRUE), widths=c(1, 6, 1),

问题 I've got a set of labels in a flowbox, the problem is that I would like for these labels to be 96px wide at most. I've set label.set_ellipsize(True), but since the flowbox gives them as much room as they like they don't get ellipsized, even though I've set their size request to 96px wide. I've tried every function I could find that seemed even tangentially related on all the widgets involved, but nothing seems to work. the only workaround I did find was using set_min_children_per_line() but

问题 A bit of a silly question but important for me to understand. As far as I know when using the inline "width" attribute in HTML, it is permitted to omit "px" - - will automatically be understood as "20px" unless percentage("20%") is used. My question is: Is it wrong to use the "..px" even though it's not needed? The code seem so much cleaner to me, it follows the same rule as CSS and least but not last - it doesn't bug me anytime I look at it. Thanks in advance. 回答1: This is never stated

问题 In my javascript file I have the following line: <div id="mygraph" style="width:200px;height:100px;"></div> I'd like to set the width and height values in the style tag from two variables that take their values from the corresponding functions: var my_width = getWidth(); var my_height = getHeight(); How can I accomplish that? I'm missing the correct syntax. Thank you in advance... 回答1: The following assumes that my_height and my_width returned by your functions are plain numbers: document
