Detailed Description

template<typename FILTERBASECLASS>
class adtf::ui::riddler::qt_ui_filter< FILTERBASECLASS >

Implementation template which implements a IQtXSystem::IWindow and a IQtXSystem::IWindowState interface and creates a window on the adtf::ui::riddler::IQtXSystem while initializing.

Template Parameters
FILTERBASECLASSa adtf::filter::hollow::cFilter implementation. The Init and Shutdown method will be override.

Member Function Documentation

◆ EnableWindowState()

void EnableWindowState ( )
inlineprotected

Enables the Window state callbacks.

We recommend to use this only within your filters CTOR.

adtf::ui::riddler::IQtXSystem::IWindowState

Definition at line 210 of file qt_ui_filter.h.

References qt_ui_filter< FILTERBASECLASS >::m_bWindowStateEnabled.

◆ GetStateIdentifier()

QString GetStateIdentifier ( ) const
inlineoverridevirtual

Get the State Identifier for the Window State callbacks "OnLoadState" and "OnSaveState".

Returns
QString The unique identifier for the Window state call.
Remarks
qt_ui_filter will return the set adtf::streaming::get_named_graph_object_full_name
See also
adtf::ui::riddler::IQtXSystem::IWindowState

Implements IQtXSystem::IWindowState.

Definition at line 183 of file qt_ui_filter.h.

References adtf::streaming::ant::get_named_graph_object_full_name().

◆ Init()

tResult Init ( typename FILTERBASECLASS::tInitStage  eStage)
inlineoverride

Override init method of the filter.

The FILTERBASECLASS init method will be called. The window is created while adtf::filter::ant::cFilter::tInitStage::StagePostConnect.

Parameters
[in]eStagecurrent init stage
Returns
Standard Return Code. Returning an error will result in breaking intializing of filtergraph.
Remarks
Use EnableWindowState within your filters CTOR to activate window state callbacks

◆ OnLoadState()

void OnLoadState ( [[maybe_unused] ] const QString &  strStateFolder)
inlineoverride

Callback function to load the internal window state from the given folder strStateFolder.

We recommend to use QSettings to save and load a window state file.

void cMyFilter::OnLoadState(const QString& strStateFolder)
{
QSettings oSettings(strStateFolder + "/my_window_state.settings", QSettings::IniFormat);
oSettings.beginGroup("my_window");
// read your state from the settings file as created within OnSaveState
oSettings.endGroup();
}
Parameters
[in]strStateFolderThe folder to save the window state files to.
Remarks
This callback will be only served if EnableWindowState call is made before!

Definition at line 191 of file qt_ui_filter.h.

◆ OnSaveState()

void OnSaveState ( [[maybe_unused] ] const QString &  strStateFolder) const
inlineoverride

Callback function to save the internal window state to the given folder strStateFolder.

We recommend to use QSettings to save and load a window state file.

void cMyFilter::OnSaveState(const QString& strStateFolder) const
{
QSettings oSettings(strStateFolder + "/my_window_state.settings", QSettings::IniFormat);
oSettings.beginGroup("my_window");
// save your window state to the settings file.
oSettings.endGroup();
}
Parameters
[in]strStateFolderThe folder to save the window state files to.
Remarks
This callback will be only served if EnableWindowState call is made before!

Definition at line 199 of file qt_ui_filter.h.

◆ Shutdown()

tResult Shutdown ( typename FILTERBASECLASS::tInitStage  eStage)
inlineoverride

Override shutdon method of the filter.

The filters shutdown method will be called. The window is destroyed while adtf::filter::ant::cFilter::tInitStage::StagePostConnect.

Parameters
[in]eStagecurrent shutdown stage
Returns
Standard Return Code. Error code will only be logged. Breaking shutdown is not possible.
