问题 In my project, I am trying to add the tip text (config) dynamically to a slider. How to do that? I need to add it dynamically because I am generating the array of variables in a "Controller", which holds the text for each value of the slider (for tip text). var slider = Ext.getCmp('slider') slider.setTipText(arrayOfVariables) //What should I do here instead?

If you have a better way of achieving the same end result, I'm willing to change it to your suggestion. Essentially, each grid is dynamically built based on different filters from the wrapping loop of this code. var p = item

问题 I'm relatively new to cross-platform mobile development, and recently have been going through some basic tutorials on how to use Sencha Touch in my app. I have been confused by what seems to me as inconsistency in their methodology. So here is my question: I am using the MVC design pattern. When defining a proxy for storing data in an app, should I do this in the Model or in the Store? I have seen both done and am not sure which is better, or the cases when each should be used. The following

问题 I have a grid with many columns, each of them has a filter, and some of the columns has a long text in the header: I added a css rule to wrap text in the header: .x-column-header-inner .x-column-header-text { white-space: pre-wrap; } In result I got filters with different height: How to make the same height filters? 回答1: I implemented the search filter with your hint.

It almost seems like that in the case when I do not use renderTo property, i think my form does not even see the iframe. here is my code thats working for the form
