A label is a static text UI element.
fabgl::uiLabel::uiLabel | ( | uiWindow * | parent, |
char const * | text, | ||
const Point & | pos, | ||
const Size & | size = Size(0, 0) , |

bool | visible = true |
||
) |
Creates an instance of the object.
parent | The parent window. A label must always have a parent window |
text | Text of the label |
pos | Top-left coordinates of the label relative to the parent |
size | The label size. If Size(0, 0) then size is automatically calculated |
visible | If true the label is immediately visible |
|
inlineinherited |
Allows to switch on or off anchors.
|
inlineinherited |
Determines the app that owns this object.
|
inherited |
Brings this window after another one.
insertionPoint | This window will be placed after insertionPoint window. If insertionPoint is nullptr this window will be placed at the first position (location of less visibility.). |
|
inherited |
Brings this window on top.
|
inherited |
Determines position of the client area.
Determines the client area bounding box.
origin | Decides the origin of returned rectangle |
Reimplemented in fabgl::uiScrollableControl, and fabgl::uiFrame.
|
inherited |
Determines the client area size.
|
inherited |
Exits from a modal window.
To open a modal window use uiApp.showModalWindow().
modalResult | An integer value to return to uiApp.showModalWindow(). |
|
inlineinherited |
Gets first child.
|
inlineinherited |
Determines the focus index (aka tab-index)
To set focus index use uiWindow.setFocusIndex().
|
inlineinherited |
Determines whether this window has children.
|
inherited |
Determines whether this window or control has focus.
To set currently focused window use uiApp.setFocusedWindow().
|
inlineinherited |
Determines whether the mouse is over this window.
This methods returns True also when the mouse is captured.
|
inline |
Sets or gets label style.
|
inlineinherited |
Gets last child.
|
inlineinherited |
Determines mouse position when left button was down.
|
inlineinherited |
|
inlineinherited |
Determines the object type.
|
inlineinherited |
Determines the parent window.
|
inlineinherited |
Determines the window position relative to parent window.
To change window position use uiApp.moveWindow().
|
inlineinherited |
Gets previous sibling.
Previous sibling is less visible than calling object.
Determines the window bounding box.
To set window position use uiApp.moveWindow(), to set window size use uiApp.resizeWindow() or uiApp.reshapeWindow().

Repaints a rectangle of this window.
rect | Rectangle to repaint |
|
inherited |
Repaints this window.
|
inlineinherited |

... | |||
) |
Sets label formatted text.
To update label content and size call uiLabel.update().
format | Format specifier like printf. |

Mouse click event delegate.
This delegate is called when the mouse button is pressed and released on the same position.
|
inherited |
Mouse double click event delegate.
This delegate is called when the mouse button is double pressed and released on the same position. To change double click time use uiAppProps.doubleClickTime of uiApp.appProps().
