## Detailed Description

## Member Type Documentation

### enum IOutputPane::Flag
flags IOutputPane::Flags

This enum type controls the behavior of the output pane when it is requested to show itself.

Constant | Value | Description
--- | --- | ---
`Core::IOutputPane::NoModeSwitch` | `0` | Does not switch between the modes.
`Core::IOutputPane::ModeSwitch` | `1` | Does switch between the modes.
`Core::IOutputPane::WithFocus` | `2` | Sets focus if canFocus returns true.
`Core::IOutputPane::EnsureSizeHint` | `4` | Ensures the use of the minimum size.

The Flags type is a typedef for QFlags<Flag>. It stores an OR combination of Flag values.

## Member Function Documentation

### IOutputPane::IOutputPane(QObject *parent = nullptr)

Constructs an output pane as the child of parent.

### `[slot]` void IOutputPane::flash()

Emits the signal `flashButton()`.

See also IOutputPane::flashButton().

### `[signal]` void IOutputPane::flashButton()

Makes the status bar button belonging to the output pane flash.

### `[slot]` void IOutputPane::hide()

Emits the signal `hidePage()`.

See also IOutputPane::hidePage().

### `[signal]` void IOutputPane::hidePage()

Hides the output pane.

### `[slot]` void IOutputPane::navigateStateChanged()

Emits the signal `navigateStateUpdate()`.

See also IOutputPane::navigateStateUpdate().

### `[signal]` void IOutputPane::navigateStateUpdate()

Notifies the output pane manager that the state of canNext, canPrevious, or canNavigate has changed and the buttons need to be updated.

### `[slot]` void IOutputPane::popup(int flags)

Emits the signal `showPage(int flags)` with the given parameter flags.

See also IOutputPane::showPage().

### `[signal]` void IOutputPane::setBadgeNumber(int number)

Displays number in the status bar button belonging to the output pane (for example, number of issues on building).

### `[slot]` void IOutputPane::setIconBadgeNumber(int number)

Emits the signal `setBadgeNumber(int number)` with the given parameter number.

See also IOutputPane::setBadgeNumber().

### `[signal]` void IOutputPane::showPage(int flags)

Shows the output pane. The parameter flags controls the behavior.

See also IOutputPane::Flags.

### `[slot]` void IOutputPane::toggle(int flags)

Emits the signal `togglePage(int flags)` with the given parameter flags.

See also IOutputPane::togglePage().

### `[signal]` void IOutputPane::togglePage(int flags)

Toggles the hide and show states of the output pane. The parameter flags controls the behavior.

See also IOutputPane::hidePage(), IOutputPane::showPage(), and IOutputPane::Flags.

### `[pure virtual]` bool IOutputPane::canFocus() const

Returns `true` when the output pane can be focused right now (for example, the search result window does not want to be focused if there are no results).

### `[pure virtual]` bool IOutputPane::canNavigate() const

Determines whether the output pane's navigation buttons can be enabled. When this returns `false`, the buttons are disabled and cannot be enabled.

See also IOutputPane::canNext() and IOutputPane::canPrevious().

### `[pure virtual]` bool IOutputPane::canNext() const

Determines whether the Next button in the output pane is enabled. Is overwritten when `canNavigate()` returns `false`.

See also IOutputPane::canNavigate(), IOutputPane::canPrevious(), and IOutputPane::goToNext().

### `[pure virtual]` bool IOutputPane::canPrevious() const

Determines whether the Previous button in the output pane is enabled. Is overwritten when `canNavigate()` returns `false`.

See also IOutputPane::canNavigate(), IOutputPane::canNext(), and IOutputPane::goToPrev().

### `[pure virtual]` void IOutputPane::clearContents()

Is called on selecting the clear button.

### `[pure virtual]` QString IOutputPane::displayName() const

Returns the translated display name of the output pane.

### `[pure virtual]` void IOutputPane::goToNext()

Is called on selecting the Next button.

See also IOutputPane::canNext().

### `[pure virtual]` void IOutputPane::goToPrev()

Is called on selecting the Previous button.

See also IOutputPane::canPrevious().

### `[pure virtual]` bool IOutputPane::hasFocus() const

Returns `true` when the output pane has focus.

See also IOutputPane::canFocus().

### `[pure virtual]` QWidget *IOutputPane::outputWidget(QWidget *parent)

Returns the output widget (as the child of parent) for the output pane.

### `[pure virtual]` int IOutputPane::priorityInStatusBar() const

Determines the position of the output pane on the status bar.

- 100 to 0 from front to end
- -1 do not show in status bar

### `[pure virtual]` void IOutputPane::setFocus()

Gives focus to the output pane window.

See also hasFocus().

### `[virtual]` QList<QWidget *> IOutputPane::toolBarWidgets() const

Returns the toolbar widgets for the output pane.

### `[virtual]` void IOutputPane::visibilityChanged(bool visible)

Gets called when the visibility is changed. visible is `true` when the output pane is now visible or `false` otherwise.
