ItemRenderer height (and height changes) not reflected in AdvancedDataGrid row

由 寵の児 提交于 2019-12-11 05:18:15
问题 I have an AdvancedDataGrid with variable row height set to true. I have written a cutsom item renderer based on the DataGroup spark component. Each row in the grid has multiple entities to display, the x position and width of the entites are based on the data of the entity itself. I have a custom layout written for the DataGroup that measures and posistions each entity based on its data. Each entity in each row can either truncate or not truncate its label. When the labels are not truncated,

Prevent selection of a particular item in spark list

问题 I have a Spark List which has a custom itemRenderer for rendering each item in the List. I wish to prevent an item in that list from being selected (based on some custom logic) by the user. What is the best way I can achieve this? Here's how my List is defined: <s:List id="myList" itemRenderer="com.sample.MyItemRenderer" /> and of course, I have a item renderer defined as the class com.sample.MyItemRenderer . 回答1: The selection of items is handled by the list alone as far as I know, so I

Issues with keyboard navigation on list with custom renderer

由 浪子不回头ぞ 提交于 2019-12-10 19:08:53
问题 We have a list that uses a custom renderer containing a label, a checkbox and two icons (which have click events). This list needs to be made WCAG 2.0 compliant and in order to do that we need the list to be keyboard navigable. The problem is with being able to move from one list item to the next and have the focus move to the label for the next/previous list item. Specifically, when the user enters the list using TAB button, the label for the first list item receives focus (highlighted box

Custom Itemrender in Datagrid with Datatip

由 大城市里の小女人 提交于 2019-12-09 22:40:16
问题 I have a datagrid with one datagridcolumn in it. Without a custom itemrenderer I can use a datatipfunction for showing a custom datatip but now I want to have a custom item render for colouring the rows differently. Therefore I extended a label and changed the data method but now my datatipfunction does not work anymore. Any ideas? thanks in advance Sebastian 回答1: I know this question is a wee bit old, however I just ran into the same problem and solved it by looking at how the standard

Flex: get column index in custom itemrenderer for spark datagrid

由 倾然丶 夕夏残阳落幕 提交于 2019-12-08 13:03:47
问题 I am trying to use the same custom renderer for all the columns in a spark DataGrid . I need to know the dataField or columnIndex based on which I can change state in my custom itemrenderer. Earlier in mx:DataGrid, this can be achieved by extending the MXDataGridItemRenderer which implements IDropInListItemRenderer and hence dataGridListData property is available. But using the spark DataGrid, I am extending the GridItemRenderer which DOES NOT implement the IDropInListItemRenderer and hence

Display List ItemRenderer Index in Flex3

问题 Is there a direct way to get the item index of the data inside an itemRenderer? I need to display the item number against each item. I am currently doing a workaround and won't allow reuse of my itemRenderer component. var index:int = model.dataColl.getItemIndex(data) + 1; itemNo = index.toString(); This is what i am using now, it works, but the concepts of component reuse and data abstraction are compromised. I am using Flex 3. 回答1: The first answer seems to be working, but slow. It takes O

Multiple CJuiAutocomplete in Yii - items not rendering

由 烂漫一生 提交于 2019-12-06 04:22:42
I need two CJuiAutocomplete items on my view page. Unfortunately - only one of them is rendering items properly. The other one - renders empty rows. I checked in firebug and the values are retrieved from database properly. Actually if I change the order of the registerScript - only the autocomplete from last registerScript renders items properly. Here is my code: <?php $this->widget('zii.widgets.jui.CJuiAutoComplete', array( 'name' => 'autocities', 'sourceUrl'=>$this->createUrl('projects/dynamicGetCities'), 'options' => array( 'minLength' => 2, 'select' => "js: function(event, ui) { $('
