KirSQLite - Flex AIR Database Manager: Part 56

Today we'll update our exporting feature, as well as start working on importing data.

Right now we can export CSV files with table data. CSV is just one of the formats that can be used for data importing and exporting. There are also other formats that I plan to implement later, such as XML files, JSON hashes, SQL strings and more.

That is why we will edit our existing export feature to be able to add more formats later much easier. First of all, we will rename most of the variables and objects starting with "csv" to ones starting with "export". Change csvData to exportData, csvHeaders to exportHeaders, csvGrid to exportGrid, csvColumns to exportColumns. You can do this using Find and Replace feature in your IDE.

Also add a new TabNavigator object to exportWindow, set its id to exportNavigator. Add one NavigatorContent container labeled CSV, add all he related csv-related components:

<mx:TitleWindow id="exportWindow" title="Export data" close="closeExportWindow();" showCloseButton="true" width="500">
<s:VGroup paddingTop="4" width="100%">
<mx:AdvancedDataGrid dataProvider="{exportData}" width="100%" height="300" id="exportGrid" />
<mx:TabNavigator width="100%" height="120" id="exportNavigator">
<s:NavigatorContent label="CSV" width="100%">
<s:VGroup width="100%" height="100%" paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10">
<mx:CheckBox id="exportHeaders" label="Include headers" selected="true" />
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>Separator: </s:Label>
<s:RadioButton groupName="csvSeparator" id="separatorComma" label="Comma" selected="true" />
<s:RadioButton groupName="csvSeparator" id="separatorSemicolon" label="Semi-colon" />
<s:RadioButton groupName="csvSeparator" id="separatorTab" label="Tab" />
<s:RadioButton groupName="csvSeparator" id="separatorPipe" label="Pipe" />
</s:HGroup>
<s:Button label="Export" click="doExportCSV();" width="100%" />
</s:VGroup>
</s:NavigatorContent>
</mx:TabNavigator>
</s:VGroup>
</mx:TitleWindow>

Now let's work on importing data. Declare a new ArrayCollection importData:

<mx:ArrayCollection id="importData">
</mx:ArrayCollection>

We need to add a new IconButton to the toolbar. I used 2 icons from FamFamFam's Silk icon pack to create a new icon called table_import.png, put it in your lib folder:

table_import.png

And use it in the new IconButton object. Set its click event handler to importTable():

<s:HGroup width="200" paddingLeft="6">
<custom:IconButton icon="@Embed('../lib/table_add.png')" toolTip="New table" enabled="{tableTree.selectedItems.length>0}" buttonMode="true" click="newTable();"/>
<custom:IconButton icon="@Embed('../lib/table_delete.png')" toolTip="Drop table" enabled="{isTableSelected}" buttonMode="true" click="dropTable();"/>
<custom:IconButton icon="@Embed('../lib/table_edit.png')" toolTip="Rename table" enabled="{isTableSelected}" buttonMode="true" click="renameTable();"/>
<custom:IconButton icon="@Embed('../lib/table_go.png')" toolTip="Copy table" enabled="{isTableSelected}" buttonMode="true" click="copyTable();"/>
<custom:IconButton icon="@Embed('../lib/table_relationship.png')" toolTip="Join table" enabled="{isTableSelected}" buttonMode="true" click="joinTable();"/>
<custom:IconButton icon="@Embed('../lib/table_save.png')" toolTip="Export table" enabled="{isTableSelected}" buttonMode="true" click="exportTable();"/>
<custom:IconButton icon="@Embed('../lib/table_import.png')" toolTip="Import table" enabled="{isTableSelected}" buttonMode="true" click="importTable();"/>
</s:HGroup>

This function creates a File object and opens a browsing window using browseForOpen() method. On SELECT event, call openImportWindow() function and send the file object as parameter:

private function importTable():void {
var file:File = new File();
file.browseForOpen("Open data file", [new FileFilter("CSV files", "*.csv"), new FileFilter("All files", "*")]);
file.addEventListener(Event.SELECT, importSelect);
function importSelect(evt:Event):void {
openImportWindow(file);
}
}

In openImportWindow(), we'll open a pop up window, so let's create it first.

Call it importWindow, set its close event listener to closeImportWindow().

Add an AdvancedDataGrid with dataProvider bound to importData, set its id to importGrid. This grid will be used to display the parsed data from the file.

After that, create a TabNavigator object called importNavigator with one NavigatorContent labeled "CSV". Inside this container, create a CheckBox with an id importHeaders and label "First line is a headers line". Under that CheckBox, add an AdvancedDataGrid with an id importColumnGrid. This grid will be used for assigning values from imported data columns to existing table columns.

After the tab navigator, add a ComboBox with an id importConflict and dataProvider set to conflictTypes. This will be used to handle conflicts during execution.

Finally, add a button labeled "Import" with a click event handler doImport():

<mx:TitleWindow id="importWindow" title="Import data" close="closeImportWindow();" showCloseButton="true" width="500">
<s:VGroup paddingTop="4" width="100%">
<mx:AdvancedDataGrid dataProvider="{importData}" width="100%" height="200" id="importGrid" />
<s:Label>Import from: </s:Label>
<mx:TabNavigator width="100%" height="200" id="importNavigator">
<s:NavigatorContent label="CSV" width="100%">
<mx:VBox width="100%" height="100%" paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10">
<mx:CheckBox id="importHeaders" label="First line is a headers line" selected="true" />
<s:Label>Assign CSV columns to table columns:</s:Label>
<mx:AdvancedDataGrid id="importColumnGrid" width="100%" height="100%"></mx:AdvancedDataGrid>
</mx:VBox>
</s:NavigatorContent>
</mx:TabNavigator>
<s:HGroup width="100%" verticalAlign="middle">
<s:Label>On conflict: </s:Label>
<mx:ComboBox id="importConflict" dataProvider="{conflictTypes}" editable="false" />
</s:HGroup>
<s:Button label="Import" click="doImport();" width="100%" />
</s:VGroup>
</mx:TitleWindow>

Now create openImportWindow() function. First we open and center the pop up, then set importData to an empty ArrayCollection and set the columns of importGrid to an array with a single AdvancedDataGridColumn labeled "Data". Check if file's extension is csv, set impotrNavigator's selectedIndex to 0. We'll do this kind of checks later to automatically set the approporiate format. For now, it's just CSV that we have.

private function openImportWindow(file:File):void {
PopUpManager.addPopUp(importWindow, this);
PopUpManager.centerPopUp(importWindow);
importData = new ArrayCollection([]);
importGrid.columns = [new AdvancedDataGridColumn("Data")];
enableEverything = false;
if (file.extension == "csv") {
importNavigator.selectedIndex = 0;
}
}

The closeImportWindow() function closes the window and doImport() does nothing:

private function closeImportWindow():void {
PopUpManager.removePopUp(importWindow);
enableEverything = true;
}

private function doImport():void{}
