Flex 4.5 NavigatorContent buttonBar Issue

JHayes — Fri, 27 Jan 2012 16:24:34 GMT

Hello!

I'm using Flash Builder 4.5 Premium and ArcGIS API for Flex 2.5.

Scenerio:
I have a buttonBar whose dataProvider is an mx:viewStack supplied by Spark NavigatorContent. I have checkBoxes inside each of the NavigatorContent instances. The checkBoxes turn content on and off. Works great.

Problem:
When you select a different button in the buttonBar the selected content from the previuos button still displays.

Question:
How do I get the selected content from the previous button to not display? I'm not sure how to do this.

Bonus:
If someone can tell me how to handle the checkBox eventHandler more efficiently that would be awesome! Because right now I currently have an eventHandler function for each check box (like 18). Since I'm still green, so I figured I'd get everything working before trying to streamline this. Or perhaps I need to add something to this code to unSelect the checkBox once the button has changed? Not sure.

Thanks for the help!

Joe

Joe,

See if this is what you are after:

            protected function CheckBox_clickHandler(event:MouseEvent):void             {                 const vis:Boolean = CheckBox(event.target).selected;                 switch(event.target.label){                     case "Bike Lane Comment":{                         bikelaneMapServer.visible = vis;                          break;                     }                     case "Sidewalk Comments":{                         sidewalkComments.visible = vis;                         break;                     }                     //etc, etc...                 }             }                          protected function viewMenu_changeHandler(event:IndexChangeEvent):void             {                 //Clear all the optional layers in the map                 bikelaneMapServer.visible = bCommentCheckBox.selected = false;                 sidewalkComments.visible = sCommentCheckBox.selected = false;                 //etc, etc...             } <s:ButtonBar id="viewMenu" left="5" right="5" top="30" height="21"                       dataProvider="{myViewStack}"                      requireSelection="true" change="viewMenu_changeHandler(event)"/>  <s:CheckBox id="sCommentCheckBox"                                  label="Sidewalk Comments"                                 fontSize="14"                                 click="CheckBox_clickHandler(event)"/>

Joe,

Glad that worked for you... But you marked your post as the answer and thus I did not recieve the points for answering your question. You have to mark the post that answers your question with the check.

Oops - I think I just fixed it.

Robert,

Thought I should update you about this code. Please see this forum post. Using the code from the other post and changing the buttonBar change event to to this works well. Thanks.

protected function viewMenu_changeHandler(event:IndexChangeEvent):void
            {
                bikelaneCheckBox.selected = false;
                sCommentCheckBox.selected = false;
                bCommentCheckBox.selected = false;
                sidewalkCheckBox.selected = false;
                opsCheckBox.selected = false;
                planningAreasCheckBox.selected = false;
            }

I know this is an older thread, but for those having similar issues or wanting to know how to control a group of radio buttons better, using the RadioButtonGroup component may be helpful. Here's a link to some examples. You can set the "selection" in ActionScript only, but setting to null should clear the selected radio button.
