Qt designer file dialog python

If you want to use sheets, use open instead. Always use the default directory icon. Some platforms allow the user to set a different icon. Custom icon lookup cause a big performance impact over network or removable drives. This enum value was added in Qt 5.

By default, this property is set to AcceptOpen. This property holds whether the filedialog should ask before accepting a selected file, when the accept mode is AcceptSave.

Use setOption DontConfirmOverwrite ,! This property specifies a string that will be added to the filename if it has no suffix already. The suffix is typically used to indicate the file type e. The file mode defines the number and type of items that the user is expected to select in the dialog. By default, this property is set to AnyFile. It is possible to set custom text after the call to. This is a convenience static function that will return an existing directory selected by the user.

This function creates a modal file dialog with the given parent widget. If parent is not None , the dialog will be shown centered over the parent widget. Either of these may be an empty string in which case the current directory and a default caption will be used respectively.

The options argument holds various options about how to run the dialog, see the Option enum for more information on the flags you can pass. To ensure a native file dialog, ShowDirsOnly must be set. If options includes DontResolveSymlinks , the file dialog will treat symlinks as regular directories. Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QFileDialog constructors.

If the user presses Cancel, it returns an empty url. The function is used similarly to getExistingDirectory. In particular parent , caption , dir and options are used in the exact same way. The main difference with getExistingDirectory comes from the ability offered to the user to select a remote directory. The supportedSchemes argument allows to restrict the type of URLs the user will be able to select.

It is a way for the application to declare the protocols it will support to fetch the file content. An empty list means that no restriction is applied the default. When possible, this static function will use the native file dialog and not a QFileDialog. This is a convenience static function that returns an existing file selected by the user. If the user presses Cancel, it returns a null string.

The function creates a modal file dialog with the given parent widget. If dir includes a file name, the file will be selected. Only files that match the given filter are shown. The filter selected is set to selectedFilter. The parameters dir , selectedFilter , and filter may be empty strings.

If caption is not specified then a default caption will be used. This is a convenience static function that will return one or more existing files selected by the user. The filter is set to filter so that only those files which match the filter are shown. The parameters dir , selectedFilter and filter may be empty strings. The function is used similarly to getOpenFileName. In particular parent , caption , dir , filter , selectedFilter and options are used in the exact same way.

The main difference with getOpenFileName comes from the ability offered to the user to select a remote file. If the user presses Cancel, it returns an empty list.

The function is used similarly to getOpenFileNames. The main difference with getOpenFileNames comes from the ability offered to the user to select remote files. This is a convenience static function that will return a file name selected by the user. The file does not have to exist. You can use Qt Designer to create and customize the user interface of your custom dialogs. With Qt Designer, you can create a dialog's GUI using a built-in template or you can create a dialog entirely from scratch.

You can add widgets to your dialogs, arrange widgets in layouts , set their appearance, provide initial values for their attributes, set their tab order, create buddies to provide keyboard shortcuts, and connect the widgets' built-in signals to slots.

When we launch Qt Designer, we are presented with the application's main window and with a dialog called New Form.

This dialog allows us to select a template for the GUI we want to create. These templates include options to create dialogs, main windows, and custom widgets.

In this tutorial, we're just interested in how to create dialogs with Qt Designer. So, we'll just cover the 3 templates Qt Designer offers for creating dialogs:.

Dialog with Buttons Bottom to create a form or dialog with an OK and a Cancel buttons horizontally-arranged on the bottom-right corner of the form. Dialog with Buttons Right to create a form with an OK and a Cancel buttons vertically-arranged on the top-right corner of the form. The following screencast shows how we can use Qt Designer to create custom dialogs using the different default dialog templates:. You can use widgets to display information, get the user's input, and provide containers for other widgets that should be grouped.

With Qt Designer, you can add widgets to our dialogs and windows by dragging and doping them from Qt Designer's Widget Box panel to your form. Once you have all the required widgets in place, you can arrange them using Qt's layouts. Say your company is creating a database application to manage the employees' relevant information. You're asked to add a new PyQt dialog to enter or update general information about employees. The dialog must include options to enter the following info: Employee name , Employment date , Department , Position , Annual salary and Job description.

The following screencast shows how we can quickly create the GUI for the dialog at hand using Qt Designer:. Here, we first create a dialog using the Dialog with Buttons Bottom template. Then, we add QLabel objects to ask for the needed information. Every field needs a specific input widget. Once we have all the widgets in place, we select all of them and arrange them using a QFormLayout object.

The final step is to add a main layout to the dialog. To do that, we use a QVBoxLayout object that allows us to arrange the widgets and the dialog's buttons in a vertical column. That's all, we've created our first dialog using Qt Designer. Let's save the dialog's GUI file with the name employee. In this section, we've used Qt Designer in Edit Widgets mode, which is the default mode. In this mode, we can add widgets to our dialogs, edit widget's properties, lay out the widgets on the dialog's GUI, and so on.

To activate the Edit Widgets mode, we can choose any of the three following options:. An element that can improve the usability of your dialogs is the tab order of the input widgets. The default tab order is based on the order in which you place the widgets on the form. This is a kind of annoying behavior. The following screencast shows the problem:. To fix this problem, we need to change the tab order of the input widgets on our dialog. In Edit Tab Order mode, each input widget in the form is shown with a number that indicates its position in the tab order chain.

We can change the tab order by clicking on the number of each widget in the correct order. You can see how to do this in the following screencast:. In this example, we change the tab order of the input widgets by clicking on each number in the correct order. When we select a number, it changes to red to indicate that this is the currently edited position in the tab order. When we click on another number, then that number will be second in the tab order, and so on. In case of a mistake, we can restart numbering by choosing Restart from the form's context menu.

To partially edit the tab order, we can select a number with the Ctrl key pressed. The tab order will be changed from that widget on. We can also right-click on a given number and then choose Start from Here from the context menu. In Qt, buddies are connections between related widgets.

These connections allow you to provide a quick keyboard shortcut to move the focus to a given input widget. By setting buddies, you'll improve the usability of your dialogs because you'll provide the user with a fast way to move around dialogs and windows. In our Annual salary QLabel , that letter could be A or s or any other letter in the text of the label.

But you can easily do it with a few lines of code. If so, than you can use the KUrlRequester for this. It can easily be configured to support anything from files to urls to directories.

QFileDialog exists in QtGui. At least in my version 4. I think the reason it is not in Designer is because it opens its own window instead of being a widget to place on another window.

Asked 11 years, 6 months ago. Or you can bypass all the designer rigmarole and just add the line self. I totally agree. I suppose that the Qt designer is somehow required to do this task. In the Slots box. So you could say it's really more a question of convenience than of creating idiomatic code. Show 3 more comments. Sign up or log in Sign up using Google.
