This item has no description. Showing description inherited from TCastleContainer.Invalidate.
Redraw the contents of of this window, at the nearest suitable time. This method does not redraw immediately (it does not call EventBeforeRender and EventRender inside), it only makes sure that they will be called very soon. Calling this on a closed container (with GLInitialized = | |

This item has no description. Showing description inherited from TCastleContainer.Width.

|
procedure EventOpen(const OpenWindowsCount: Cardinal); override; |
|
This item has no description. Showing description inherited from TCastleContainer.EventOpen. Propagate the event to all the Controls and to our own OnXxx callbacks. These methods are called automatically when necessary, so usually you don't call them. But in rare cases, it makes sense to "fake" some event by calling these methods. Most of these methods are called automatically by the container owner, like TCastleWindow or TCastleControl. Some are called by EventUpdate, which is special in this regard, as EventUpdate is not only responsible for calling TCastleUserInterface.Update on all Controls, it also calls EventJoyAxisMove, EventJoyButtonPress, EventSensorRotation, EventSensorTranslation. | |

When the DesignUrl is set you can use this method to find loaded components. Like this: MyButton := MyCastleControl.DesignedComponent('MyButton') as TCastleButton;
When the name is not found, raises exception (unless Required is See also

Properties
|
property DesignUrl: String read FDesignUrl write SetDesignUrl; |
|
Load and show the design (.castle-user-interface file). You can reference the loaded components by name using DesignedComponent. If you have more complicated control flow, we recommend to leave this property empty, and split your management into a number of states (TCastleView) instead. In this case, load design using TCastleView.DesignUrl. This property makes it however easy to use .castle-user-interface in simple cases, when TCastleControl just shows one UI. The design loaded here is visible also at design-time, when editing the form in Lazarus/Delphi. Though we have no way to edit it now in Lazarus/Delphi (you have to use CGE editor to edit the design), so it is just a preview in this case. See https://castle-engine.io/control_on_form for documentation how to use TCastleControl. | |
