EllipsizeChoiceBox()

void KIPLATFORM::UI::EllipsizeChoiceBox

(

wxChoice *

aChoice

)

Configure a wxChoice control to ellipsize the shown text in the button with the ellipses placed at the end of the string.

Parameters

aChoice

is the choice box to ellipsize

    GtkCellRenderer* cell = (GtkCellRenderer*) cells->data;

    // Only the list of cells must be freed, the renderer isn't ours to free
    g_list_free( cells );

ForceFocus()

void KIPLATFORM::UI::ForceFocus

(

wxWindow *

aWindow

)

Pass the current focus to the window.

On OSX this will forcefully give the focus to the desired window, while on MSW and GTK it will simply call the wxWidgets SetFocus() function.

Parameters

aWindow

is the window to pass focus to

    aWindow->SetFocus();

GetSystemScaleFactor()

double KIPLATFORM::UI::GetSystemScaleFactor

(

const wxWindow *

aWindow

)

Tries to determine the system scaling factor currently in use for the window.

Under wx3.0, GTK fails to properly detect the scale factor.

Parameters

aWindow

pointer to the window to check

Returns

System scale factor in use, defaulting to the wxWidgets method

{
    double val = 1.0;

    GtkWidget* widget = static_cast<GtkWidget*>( aWindow->GetHandle() );

    if( widget && gtk_check_version( 3, 10, 0 ) == nullptr )
        val = gtk_widget_get_scale_factor( widget );

    return val;

IsDarkTheme()

bool KIPLATFORM::UI::IsDarkTheme

(

)

Determine if the desktop interface is currently using a dark theme or a light theme.

Returns

true if a dark theme is being used.

IsStockCursorOk()

bool KIPLATFORM::UI::IsStockCursorOk

(

wxStockCursor

aCursor

)

Checks if we designated a stock cursor for this OS as "OK" or else we may need to load a custom one.

Parameters

aCursor

is wxStockCursor we want to see if its acceptable

IsWindowActive()

bool KIPLATFORM::UI::IsWindowActive

(

wxWindow *

aWindow

)

Check to see if the given window is the currently active window (e.g.

the window in the foreground the user is interacting with).

Parameters

aWindow

is the window to check

ReparentQuasiModal()

void KIPLATFORM::UI::ReparentQuasiModal

(

wxNonOwnedWindow *

aWindow

)

Move a window's parent to be the top-level window and force the window to be on top.

This only has an affect for OSX, it is a NOP for GTK and MSW.

Apple in its infinite wisdom will raise a disabled window before even passing us the event, so we have no way to stop it. Instead, we must set an order on the windows so that the quasi-modal will be pushed in front of the disabled window when it is raised.

Parameters

aWindow

is the window to reparent
