No doubt, the VCL FileDialogs offer a multitude of configuration options that cover most standard use cases. But sometimes this might not be enough and you want to create a specialized custom dialog with a different layout, additional controls (e.g. for import/export dialogs) or different looks. Rebuilding the dialog from scratch, including all the file system related components, will however in most cases not be a feasible alternative. At this point, the ShellBrowser Components can fill the gap quite comfortably: All the Win32 shell related functionality is wrapped into easy-to-use components so you can concentrate on your special use case. You can obtain a trial version of the ShellBrowser Components via Embarcadero’s GetIt Package Manager or using the link at the end of this article. After installation, you will find the ShellBrowser components in the “JAM Software” section of the component palette. The Windows Explorer style The quickest way is using a “TJamExplorerBrowser” component as the main building block of the dialog. Similar to the FileDialog components of VCL, ExplorerBrowser is built around a Windows COM object, representing a configurable file system browser which shares most parts with the Windows File Explorer. Using the “VisiblePanes” property, you can configure what parts of the control you want to show (the folder view on the right side cannot be hidden). Other design time options for the control include setting the path or “Special Folder” – a collection of named locations, including file system folders (e.g. SF_DOWNLOADS) and virtual folders (SF_DRIVES), as well as different filtering and view settings. To make the dialog complete, we’ll add two more typical file dialog components, the “TJamOpenSaveComboBox” for the file name to be opened or saved, and the “TJamFilterCombo” for specifying file extension filters which can be applied. Keeping controls in sync There is no need to write code to synchronize the components! This can be done using a “TJamShellLink”. You can simply drop an instance from the component palette and assign it as the “ShellLink” property of the ShellBrowser controls that should be synchronized. Let me show you in this small example: All ShellBrowser controls on the form use the same ShellLink. TJamShellLink synchronizes selected paths, files and filters among attached controls. The ShellLink can be used to restrict navigational access to an allowed range of folders, too. In the example below, it will apply the filter that is set in the TJamFilterCombo to ExplorerBrowser, set the text of the “TJamOpenSaveComboBox” to the file name that is selected in ExplorerBrowser and navigate to the path that the user types in the TJamOpenSaveComboBox in ExplorerBrowser. Using the ExplorerBrowser as the main file system component in this example has the benefit that – being a Windows control – it looks and behaves exactly like Windows Explorer. The drawback is that not all details of appearance or behavior can be accessed or modified. E.g. there is no way to filter the visible root nodes of the navigation tree; ExplorerBrowser also does not support VCL Styles or any other form of dark theme. Even more control: TJamShellTree and TJamShellList As an alternative approach, the ExplorerBrowser component can be replaced by various other ShellBrowser controls, such as the TJamShellList, TJamShellTree and TJamShellBreadCrumbBar. These are not based on a Windows COM object, but replicate its look and behavior as closely as […]

Themba Sivate has been a Delphi programmer since 2012. He introduced his application (ST Audio Player Lite) at the Delphi 26th Showcase Challenge and we got to converse with him to have an insight on his Delphi expertise. Find out more about his software at ST Software When did you start using RAD Studio/Delphi and have long have you been using it? I started using RAD Studio on 2012 at University. A year later, I started to learning building applications from scratch using C++ builder installed on institution’s machines, until today. What was it like building software before you had RAD Studio/Delphi? I tried both QT Creator and visual studio before, and it was a pain and limitations too. Rad Studio will let you call Delphi code within C++. Meaning you can reuse Delphi libraries on c++, How did RAD Studio/Delphi help you create your showcase application? RAD Studio is easy to use, simplified drag and drop, simplified packaging. It help me to complete my audio player in less time. What made RAD Studio/Delphi stand out from other options? Easy to use, backwards compatibility, tons of libraries/components, simplified drag and drop, cross-platform outputs. What made you happiest about working with RAD Studio/Delphi? Less development time. Good database handling and development. Its sad that the I cant afford the license at this stage, but I’d be happy to build the list of applications I had on my mind which requires a paid version of RAD Studio. What have you been able to achieve through using RAD Studio/Delphi to create your showcase application? Debugging was pretty easy and straight forward. Most can be achieved by modifying values of the properties, without writing a line code. What are some future plans for your showcase application? I’m planning to upload it on windows store. Future releases are planned and bug fixes. Also planned to support multiple languages. Thank you, Themba! You can check out his software’s showcase entry below. Showcase

Dashboards, a graphical visualization of data, seem to be everywhere, especially in these pandemic times where daily and weekly trends take on a very personal significance. In this article we are going to look at a beautiful dashboard which you can very easily customize to suit your own needs. Visualization is the art of making the useful, beautiful. There is only so far you can get with tables of facts and figures. Sooner or later there comes a time when you will need to create a graphical visualization of your data. Pictures really do save a thousand words, but they also help your users get a grasp of the information in a more easily consumed way. Most Delphi programmers are probably familiar with the basic TChart component which has been bundled with nearly every version of Delphi. For more recent versions of RAD Studio such as Sidney, you had to tick an optional checkbox to get the TChart component to appear on your component palette. That bundled version of the TChart component is provided by Steema Software based in Spain. The dashboard we are writing about here is also produced by Steema to demonstrate the power of their Pro versions of TeeChart as well as their TeeGrid. More on that in a moment. What does the dashboard visualization look like? It’s beautiful! Where can you get the dashboard visualization? The great news is the Steema dashboard example is freely available for download from GitHub here: https://github.com/Steema/TeeChart-FireMonkey-samples/tree/master/Dashboard I used the cross-platform GitHub desktop project to download the sample directly from the repository. What components do you need? To work with Steema’s dashboard visualization example you’re going to need a copy of their Pro TeeChart component. This is NOT the same as the bundled version. In fact, if you have the bundled version installed you will need to completely uninstall it first because it will clash with the Pro version. You will also need to install Steema’s TeeGrid component too. What if I don’t have the TeeChart Pro or TeeGrid component packs? Not a problem – Steema’s website has a download for a fully functional 30-day trial of both component libraries. I used the trial versions to write this article and they worked without any problems. Go to this link to download them: https://www.steema.com/product/vcl Just make sure you uninstall the bundled version of TeeChart that came with RAD Studio FIRST because I didn’t remember and got myself into a bit of tangle. If that happens to you, uninstall both the new component packs using their uninstaller. Then go into the IDE, select “component” from the menu, then “install packages”. Now scroll down and make sure all references to the TeeChart and TeeGrid components are gone. Click on any that are there, and then “remove”. Now close the IDE and install the TeeChart Pro and TeeGrid components using their installers, and all will be well. I make these mistakes, so you don’t have to! What does the dashboard visualization do? Well, the source code reads from an included SQLite database. Almost all the data retrieval is done using LiveBindings. All the data access components use the FireDAC query components. There are a few areas in the program where the data is read and manipulated in code but overall, it’s nearly all the LiveBindings […]
