ReadOnlyPart Class Reference
from PyKDE4.kparts import *
Inherits: KParts.Part → QObject
Subclasses: KParts.ReadWritePart
Namespace: KParts
Detailed Description
- Abstract class:
- This class can be used as a base class for new classes, but can not be instantiated directly.
Method Documentation
| __init__ | ( | self, | ||
| QObject | parent=0 | |||
| ) |
Constructor See also Part for the setXXX methods to call.
| __init__ | ( | self, | ||
| ReadOnlyPartPrivate | dd, | |||
| QObject | parent | |||
| ) |
| __init__ | ( | self, | ||
| KParts.ReadOnlyPart | a0 | |||
| ) |
| abortLoad | ( | self ) |
- Internal:
| KParts.OpenUrlArguments arguments | ( | self ) |
- Returns:
- the arguments that were used to open this URL.
| KParts.BrowserExtension browserExtension | ( | self ) |
This convenience method returns the browserExtension for this part, or 0 if there isn't any.
| canceled | ( | self, | ||
| QString | errMsg | |||
| ) |
Emit this if loading is canceled by the user or by an error.
- Parameters:
-
errMsg the error message, empty if the user canceled the loading voluntarily.
- Signal syntax:
QObject.connect(source, SIGNAL("canceled(const QString&)"), target_slot)
| bool closeStream | ( | self ) |
Terminate the sending of data to the part. With some data types (text, html...) closeStream might never actually be called, in the case of continuous streams, for instance plain text or HTML data.
| bool closeUrl | ( | self ) |
Called when closing the current url (e.g. document), for instance when switching to another url (note that openUrl() calls it automatically in this case). If the current URL is not fully loaded yet, aborts loading. Deletes the temporary file used when the url is remote.
- Returns:
- always true, but the return value exists for reimplementations
| completed | ( | self ) |
Emit this when you have completed loading data. Hosting apps will want to know when the process of loading the data is finished, so that they can access the data when everything is loaded.
- Signal syntax:
QObject.connect(source, SIGNAL("completed()"), target_slot)
| completed | ( | self, | ||
| bool | pendingAction | |||
| ) |
Same as the above signal except it indicates whether there is a pending action to be executed on a delay timer. An example of this is the meta-refresh tags on web pages used to reload/redirect after a certain period of time. This signal is useful if you want to give the user the ability to cancel such pending actions.
pendingAction true if a pending action exists, false otherwise.
- Signal syntax:
QObject.connect(source, SIGNAL("completed(bool)"), target_slot)
| guiActivateEvent | ( | self, | ||
| KParts.GUIActivateEvent | event | |||
| ) |
Reimplemented from Part, so that the window caption is set to the current url (decoded) when the part is activated This is the usual behavior in 99% of the apps Reimplement if you don't like it - test for event->activated() !
Technical note : this is done with GUIActivateEvent and not with PartActivateEvent because it's handled by the mainwindow (which gets the even after the PartActivateEvent events have been sent)
| bool isLocalFileTemporary | ( | self ) |
- Internal:
| bool isProgressInfoEnabled | ( | self ) |
Returns whether the part shows the progress info dialog used by internal KIO job.
| QString localFilePath | ( | self ) |
Returns the local file path associated with this part.
| bool openFile | ( | self ) |
- Abstract method:
- This method is abstract and can be overridden but not called directly.
If the part uses the standard implementation of openUrl(), it must reimplement this, to open the local file. Otherwise simply define it to { return false; }
Initiate sending data to this part. This is an alternative to openUrl, which allows the user of the part to load the data itself, and send it progressively to the part.
- Parameters:
-
mimeType the type of data that is going to be sent to this part. url the URL representing this data. Although not directly used, every ReadOnlyPart has a URL (see url()), so this simply sets it.
- Returns:
- true if the part supports progressive loading and accepts data, false otherwise.
| bool openUrl | ( | self, | ||
| KUrl | url | |||
| ) |
Only reimplement openUrl if you don't want the network transparency support to download from the url into a temporary file (when the url isn't local). Otherwise, reimplement openFile() only .
If you reimplement it, don't forget to set the caption, usually with emit setWindowCaption( url.prettyUrl() );
| setArguments | ( | self, | ||
| KParts.OpenUrlArguments | arguments | |||
| ) |
Sets the arguments to use for the next openUrl call.
| setLocalFilePath | ( | self, | ||
| QString | localFilePath | |||
| ) |
Sets the local file path associated with this part.
| setLocalFileTemporary | ( | self, | ||
| bool | temp | |||
| ) |
- Internal:
| setProgressInfoEnabled | ( | self, | ||
| bool | show | |||
| ) |
Call this to turn off the progress info dialog used by the internal KIO job. Use this if you provide another way of displaying progress info (e.g. a statusbar), using the signals emitted by this class, and/or those emitted by the Job given by started.
| setUrl | ( | self, | ||
| KUrl | url | |||
| ) |
Sets the url associated with this part.
| showProgressInfo | ( | self, | ||
| bool | show | |||
| ) |
| started | ( | self, | ||
| KIO.Job | a0 | |||
| ) |
The part emits this when starting data. If using a KIO.Job, it sets the job in the signal, so that progress information can be shown. Otherwise, job is 0.
- Signal syntax:
QObject.connect(source, SIGNAL("started(Job*)"), target_slot)
| KUrl url | ( | self ) |
Returns the URL currently opened in this part.
- Returns:
- The current URL.
| bool writeStream | ( | self, | ||
| QByteArray | data | |||
| ) |
Send some data to the part. openStream must have been called previously, and must have returned true.
- Returns:
- true if the data was accepted by the part. If false is returned, the application should stop sending data, and doesn't have to call closeStream.
