◆ currentLocationUrl

readwrite |
Definition at line 44 of file kcoreurlnavigator.h.
◆ historyIndex
|
read |
The history index of the current location, where 0 <= history index < KCoreUrlNavigator::historySize().
0 is the most recent history entry.
Definition at line 84 of file kcoreurlnavigator.h.
◆ historySize
|
read |
The amount of locations in the history.
The data for each location can be retrieved by KCoreUrlNavigator::locationUrl() and KCoreUrlNavigator::locationState().

Member Function Documentation
◆ currentLocationUrl()
QUrl KCoreUrlNavigator::currentLocationUrl | ( | ) | const |
Definition at line 164 of file kcoreurlnavigator.cpp.
◆ currentUrlAboutToChange()
Is emitted, before the location URL is going to be changed to newUrl.
The signal KCoreUrlNavigator::urlChanged() will be emitted after the change has been done. Connecting to this signal is useful to save the state of a view with KCoreUrlNavigator::saveLocationState().
◆ goBack()
bool KCoreUrlNavigator::goBack | ( | ) |
Goes back one step in the URL history.
The signals KCoreUrlNavigator::urlAboutToBeChanged(), KCoreUrlNavigator::urlChanged() and KCoreUrlNavigator::historyChanged() are emitted if true is returned. False is returned if the beginning of the history has already been reached and hence going back was not possible. The history index (see KCoreUrlNavigator::historyIndex()) is increased by one if the operation was successful.
Definition at line 117 of file kcoreurlnavigator.cpp.
◆ goForward()
bool KCoreUrlNavigator::goForward | ( | ) |
Goes forward one step in the URL history.
The signals KCoreUrlNavigator::urlAboutToBeChanged(), KCoreUrlNavigator::urlChanged() and KCoreUrlNavigator::historyChanged() are emitted if true is returned. False is returned if the end of the history has already been reached and hence going forward was not possible. The history index (see KCoreUrlNavigator::historyIndex()) is decreased by one if the operation was successful.
Definition at line 135 of file kcoreurlnavigator.cpp.
◆ goUp()
bool KCoreUrlNavigator::goUp | ( | ) |
Goes up one step of the URL path and remembers the old path in the history.
The signals KCoreUrlNavigator::urlAboutToBeChanged(), KCoreUrlNavigator::urlChanged() and KCoreUrlNavigator::historyChanged() are emitted if true is returned. False is returned if going up was not possible as the root has been reached.
Definition at line 152 of file kcoreurlnavigator.cpp.
◆ historyChanged()
Q_SIGNAL void KCoreUrlNavigator::historyChanged | ( | ) |
Is emitted, if the history has been changed.
Usually the history is changed if a new URL has been selected.
◆ historyIndex()
int KCoreUrlNavigator::historyIndex | ( | ) | const |
Definition at line 257 of file kcoreurlnavigator.cpp.
◆ historySize()
int KCoreUrlNavigator::historySize | ( | ) | const |
Definition at line 252 of file kcoreurlnavigator.cpp.
◆ locationState()
QVariant KCoreUrlNavigator::locationState | ( | int | historyIndex = -1 | ) | const |
- Returns
- Location state given by historyIndex. If historyIndex is smaller than 0, the state of the current location is returned.
Definition at line 111 of file kcoreurlnavigator.cpp.
◆ locationUrl()
QUrl KCoreUrlNavigator::locationUrl | ( | int | historyIndex = -1 | ) | const |
- Returns
- URL of the location given by the historyIndex. If historyIndex is smaller than 0, the URL of the current location is returned.
Definition at line 100 of file kcoreurlnavigator.cpp.
◆ saveLocationState()
void KCoreUrlNavigator::saveLocationState | ( | const QVariant & | state | ) |
Saves the location state described by state for the current location.
It is recommended that at least the scroll position of a view is remembered and restored when traversing through the history. Saving the location state should be done when the signal KCoreUrlNavigator::urlAboutToBeChanged() has been emitted. Restoring the location state (see KCoreUrlNavigator::locationState()) should be done when the signal KCoreUrlNavigator::urlChanged() has been emitted.
Example:
Definition at line 106 of file kcoreurlnavigator.cpp.
◆ setCurrentLocationUrl()
void KCoreUrlNavigator::setCurrentLocationUrl | ( | const QUrl & | url | ) |
Definition at line 169 of file kcoreurlnavigator.cpp.
◆ urlSelectionRequested()
When the URL is changed and the new URL (e.g. /home/user1/) is a parent of the previous URL (e.g. /home/user1/data/stuff), then this signal is emitted and url
is set to the child directory of the new URL which is an ancestor of the old URL (in the example paths this would be /home/user1/data/).
This signal allows file managers to pre-select the directory that the user is navigating up from.
