◆ noOthersInGrpSelected()

bool Isis::TabBar::noOthersInGrpSelected ( const int &  index) const
private
Parameters
indexIndex of the Tab. The first Tab added to the bar has an index of 0. The last Tab added has an index of size() - 1.
Returns
True if there are no other Tabs in the given Tab's radio group which are selected, false otherwise.

◆ radioStyle()

◆ setEnabled()

void Isis::TabBar::setEnabled ( bool  newEnabledStatus)

Custom setEnabled method that also calls setEnabled for each of our Tabs.

Parameters
newEnabledStatusThe new enabled status that will be applied to the TabBar and all of its Tabs

Definition at line 139 of file TabBar.cpp.

References size().

◆ setRadioStyle()

void Isis::TabBar::setRadioStyle ( const bool &  radioStyle)

If set to true then the effect is that Tabs in the same radio group can only be selected one at a time.

When a Tab is selected all other Tabs in the same radio group would automatically be deselected. If set to false then all Tabs in the TabBar will behave independent from eachother regardless of how their radio groups are set.

Parameters
radioStyleTrue if radio style should be used, false otherwise

Definition at line 66 of file TabBar.cpp.

References radioStyle().

◆ setSelected()

void Isis::TabBar::setSelected ( const int &  index,
const bool &  status 
)

Sets whether the Tab at the specified index is selected or not.

Parameters
indexIndex of the Tab. The first Tab added to the bar has an index of 0. The last Tab added has an index of size() - 1
statusTrue if the Tab should be selected, false otherwise

Definition at line 98 of file TabBar.cpp.

References size().

◆ size()

int Isis::TabBar::size ( ) const
Returns
The number of Tabs currently in the TabBar

◆ tabClicked

void Isis::TabBar::tabClicked ( const int &  index)
privateslot

SLOT which performs actions that need to be done when we get a SIGNAL from a Tab telling us that it has been clicked.

What happens is that first the Tab is clicked. The Tab catches this signal and then emits its own clicked SIGNAL which contains its index. This SIGNAL is connected to this SLOT which then takes the appropriate action depending on a couple things. If radioStyle is not being used or if it is but there are no other Tabs in this Tab's radio group then we simply want to toggle the state of the Tab. If radio style is being used and there are others in this Tab's radio group which are selected then the other Tabs are first deselected before the Tab is set to be selected (We know it was not selected before since there was another Tab in its group which was).

Parameters
indexIndex of the Tab which emitted the clicked SIGNAL.
