阅读更多关于关于extjs的tabpanel加载tab项并且tab项以iframe显示时的页面刷新问题

近来的项目中用到了Extjs 的TabPanel,这也是Extjs最基本，最常用的组件了网上或者书上的例子里大都是把tab项渲染到一个div中，这对于在每个Tab页里加载一个页面的情况就不适合了用ifame加载不同的页面应该是最合适的方式网上也有用ifame显示子项的例子，是把每一个子项都渲染成了一个ifame 感觉这样有问题，因为切换TabPanel的子项时，子页面不刷新可能是因为每个ifame里对应的内容都都加载到了主页面，再切换时就不重新加载页面了同时发现ifame对应的页面里再有js弹出窗口的话，窗体的返回值也取不到而且采用这种方式，文档结构树上会有多个iframe ！加载多ifame的代码如下： <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" " http://www.w3.org/TR/html4/strict.dtd "> <HTML> <HEAD> <TITLE></TITLE> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <link rel="stylesheet" type="text/css" href="http://blog.163.com/baihongtao_618/blog/http:/

This is an extension of my previous question . Now I am not able to extend the height of my main panel. This is my code below library(shiny) library(shinydashboard) library(shinyBS) library(DT) ui <- dashboardPage( dashboardHeader(), dashboardSidebar( sidebarPanel( textInput("text", "Enter Id:"), box(width = 1, background = 'purple'), actionButton("Ok", "Press Ok",style='padding:8px; font-size:100%') ) ), dashboardBody( mainPanel(width = 12, tabsetPanel( tabPanel("About", value=1, h6("The objective is to test width of ShinyApp in tabPanel design", br(), br(), "Distribution Prototype" ) ),

GWT Datagrid does not show data , but contains it

阅读更多关于 GWT Datagrid does not show data , but contains it

I'm trying to convert a cellTable into a datagrid , because I want to add a search handler later and therefor I need fixed column headers. At the moment I extend the celltable / datagrid class and put the widget into a simplelayoutpanel and add this to my tabpanel . If I use the celltable , all works fine and the data shows up. If I change the type of the class to datagrid , the data shows sometimes up (The column names are always there). To add something to the table I used setRowData or a dataProvider . If I set breakpoints to delay the loading of the table content, the table does sometimes

JavaFX TabPane - One controller for each tab

阅读更多关于 JavaFX TabPane - One controller for each tab

I'm new to Fx. I have a TabPanel with 10 Tabs. Each Tab has many controls (charts, buttons, etc.), and what I want is to assign a controller for each Tab. The SceneBuilder only let me assign a controller for the whole view, I mean, only the top panel (the root) has the "Controller class" option, so I have to write the code for all the tabs in one class and this, as entail, resulting in a very large class and difficult to understand and maintain. Perhaps the solution is very simple, but as I say, I have very little experience with FX and I have not been able to find something similar on the web

R Shiny - add tabPanel to tabsetPanel dynamically (with the use of renderUI)

阅读更多关于 R Shiny - add tabPanel to tabsetPanel dynamically (with the use of renderUI)

I am developing a shiny application in which I use tabsetPanel , which is generated when user enters some particular input. Thus, I want to use renderUI function to make a tabsetPanel appear / disappear. My struggle now is that number of tabPanel elements (arguments of tabsetPanel ) also depends on user input , in the way: sometimes I need 1 one, other times I want more tabPanels . How to make it? I tried including conditionPanel or including simple if()... condition in the tabsetPanel argument, but it (rather not surprisingly...) did not work. Here you go. The code is fairly self explanatory.
