custom-component

I am trying to create a Custom Flex Component using the Flex Component framework: http://www.adobe.com/livedocs/flex/3/html/help.html?content=ascomponents_advanced_3.html . All good components allow you to define their dimensions using percentage values using: MXML: TextInput width="100%" or Actionscript at runtime: textinp.percentWidth = 100; My question is how do you implement percentage width/height in the measure() method of your custom component? More specifically, these percentages are converted to pixels values at some stage, how is this done? The way Flex layouting works is by letting

Angular 1.5 component communication suggestions usually have output bindings to invoke methods on root controllers. Let's say I have a root component, and two child components. <root> <child-1></child-1> <child-2></child-2> </root> It'd like to react to a button click on component one by reading a value on component two and then doing something in the root. For example, child-1 is a directive which wraps a drawing library that attaches a drawing to its DOM node and has a variable to control that drawing. child-2 has a button. When it is clicked, data from the child-1 variable should be passed

We are migrating JSF1.2 to JSF2 application and I have bumped into a problem with custom components.

I am currently trying to disable the selectable / editable / or change the textInput to dynamic to get my desired result. I've got a custom datagrid with dropdowns and text input areas. However, if there is no data in my Model # column, I do not want to allow for any entry in the corresponding PurchasePrice cell. col1 = new DataGridColumn("Model"); col1.headerText = "Model #"; c2.consumables_dg.addColumn(col1); col1.width = 60; col1.editable = false; col1.sortable = false; col1.cellRenderer = AlternatingRowColors_editNum_PurchasePrice; col1 = new DataGridColumn("PurchasePrice"); col1

In Delphi 2007, working on a project which includes a custom component, I'm getting this set of warnings as the first four in Messages when I do a full build (but not when I do a straight compile): [DCC Warning] Dialogs.pas(1426): W1002 Symbol 'TFileOpenDialog' is specific to a platform [DCC Warning] Dialogs.pas(1446): W1002 Symbol 'TFileSaveDialog' is specific to a platform [DCC Warning] ComCtrls.pas(6757): W1036 Variable 'Section' might not have been initialized [DCC Warning] ComCtrls.pas(19268): W1023 Comparing signed and unsigned types - widened both operands I generally try to eliminate

I'm getting a null pointer exception in my custom view (which is derived from a LinearLayout ) because it can't find its child views.
