The WindowInfoControl class is a smart pointer that is tied to a database object. This object allows you to query various attributes about a window, such as its size and aspect ratio.
◆ WindowInfoControl() [1/3]
| HPS::WindowInfoControl::WindowInfoControl |
( |
WindowKey & |
in_window | ) |
|
|
explicit |
Initializes a control tied to the window segment in_window.
◆ WindowInfoControl() [2/3]
Initializes a control tied to the same object as in_that.
◆ WindowInfoControl() [3/3]
The move constructor creates a WindowInfoControl by transferring the underlying impl of the rvalue reference to this WindowInfoControl thereby avoiding a copy and allocation.
- Parameters
-
◆ ~WindowInfoControl()
| HPS::WindowInfoControl::~WindowInfoControl |
( |
| ) |
|
Releases a reference to the database object this control is tied to.
◆ ObjectType()
| HPS::Type HPS::WindowInfoControl::ObjectType |
( |
| ) |
const |
|
inlinevirtual |
This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).
- Returns
- The declared type of the object in question, which may differ from the true, underlying type.
Reimplemented from HPS::Control.
◆ operator=() [1/2]
The move assignment operator transfers the underlying impl of the rvalue reference to this WindowInfoControl thereby avoiding a copy.
- Parameters
-
- Returns
- A reference to this WindowInfoControl.

| const |
Shows the maximum texture size that can be used.
- Parameters
-
| out_width | The maximum texture width that can be used. |
| out_height | The maximum texture height that can be used. |

inlinevirtual |
This function returns the true type of the underlying object. This function is useful for finding the type of smart pointer objects that have been cast to more generic types.
- Warning
- This function must synchronize the database (by waiting for all pending database operations to complete) in order to know the type status of this object with certainty. Therefore this function can negatively impact performance. You should vigorously avoid using this function in high-traffic or peformance-critical areas of your code.
- Returns
- The true type of the object in question.
