Rect fabgl::uiWindow::clientRect ( uiOrigin  origin)
virtualinherited

Determines the client area bounding box.

Parameters
originDecides the origin of returned rectangle
Returns
The window client area bounding box

Reimplemented in fabgl::uiScrollableControl, and fabgl::uiFrame.

inherited

Determines the client area size.

Returns
The client area size

◆ exitModal()

void fabgl::uiWindow::exitModal ( int  modalResult)
inherited

Exits from a modal window.

To open a modal window use uiApp.showModalWindow().

Parameters
modalResultAn integer value to return to uiApp.showModalWindow().

◆ firstChild()

uiWindow* fabgl::uiWindow::firstChild ( )
inlineinherited

Gets first child.

Returns
First uiWindow object

◆ focusIndex()

int fabgl::uiWindow::focusIndex ( )
inlineinherited

Determines the focus index (aka tab-index)

To set focus index use uiWindow.setFocusIndex().

Returns
The focus index

◆ hasChildren()

bool fabgl::uiWindow::hasChildren ( )
inlineinherited

Determines whether this window has children.

Returns
True if window has one o more children

◆ hasFocus()

bool fabgl::uiWindow::hasFocus ( )
inherited

Determines whether this window or control has focus.

To set currently focused window use uiApp.setFocusedWindow().

Returns
True if this window has focus

◆ isMouseOver()

bool fabgl::uiWindow::isMouseOver ( )
inlineinherited

Determines whether the mouse is over this window.

This methods returns True also when the mouse is captured.

Returns
True if the mouse is over the window

uiWindow* fabgl::uiWindow::lastChild ( )
inlineinherited

Gets last child.

Returns
Last uiWindow object

◆ max()

int fabgl::uiSlider::max ( )
inline

Gets maximum position.

Returns
Maximum position

◆ min()

int fabgl::uiSlider::min ( )
inline

Gets minimum position.

Returns
Minimum position

◆ mouseDownPos()

Point fabgl::uiWindow::mouseDownPos ( )
inlineinherited

Determines mouse position when left button was down.

Returns
Mouse position

◆ next()

uiWindow* fabgl::uiWindow::next ( )
inlineinherited

Gets next sibling.

Next sibling is more visible than calling object.

Returns
Next uiWindow object

◆ objectType()

uiObjectType& fabgl::uiObject::objectType ( )
inlineinherited

Determines the object type.

Returns
Object type.

◆ parent()

uiWindow* fabgl::uiWindow::parent ( )
inlineinherited

Determines the parent window.

Returns
Parent window

◆ pos()

Point fabgl::uiWindow::pos ( )
inlineinherited

Determines the window position relative to parent window.

To change window position use uiApp.moveWindow().

Returns
The top left point where this window is located

◆ position()

int fabgl::uiSlider::position ( )
inline

Determines slider position.

Returns
Slider position

◆ prev()

uiWindow* fabgl::uiWindow::prev ( )
inlineinherited

Gets previous sibling.

Returns
Previous uiWindow object

◆ rect()

Rect fabgl::uiWindow::rect ( uiOrigin  origin)
inherited

Determines the window bounding box.

To set window position use uiApp.moveWindow(), to set window size use uiApp.resizeWindow() or uiApp.reshapeWindow().
