I have a project where I'd like to have many wxPanel which are displayed or hide, depending the selection of the user. All panel are on the same position, only one is displayed at a time.
On a code side, there is no problem at all. Where it gets tricky, is how to manage this with wxSmith and keep a clear view while having many wxpanel at the sample location?
One way which is really not proper is to user the wxNotebook, and then when you start the soft delete all tabs and then show the needed panel.
I have look around to try to have the panel on a "other" wxSmith window and then load it, like a class but haven't find anything good.
I'm sure, as wxSmith is really a great tool that it must have a way to do this.
Thanks for your help!
See ya
"One way which is really not proper is to user the wxNotebook, and then when you start the soft delete all tabs and then show the needed panel."
Why not? I use that technique for AtomWeaver, and it works fine. The plus side is that you can design each page normally on a RAD GUI builder.
I've created a class called GUI_NotebookPageData that holds a pointer to a single notebook page. Create an array of these, holding info about all notebook pages.
Then, by index, or by name, get the info of the page you want to show/hide, and use wxNotebook's RemovePage()/InsertPage() methods.
This method is specially good for having several pages shown at the same time.
Actually it's possible to use external ressources with wxSmith, then it's very simple to manage the frames.
It create a derived class from wxPanel (or other window) on a new wxSmith window, easy to manage then just required to include it on the project.

I am trying to add a couple of ad widgets to my website http://yankeedesi.com. Please see the two widgets in the right panel. I created the widgets using the amazon associates interface and it showed up fine. However, when I try to change the style to gallery and transition to zoom and save it, the changes are not reflecting in my site. I am clicking on "Save" and then "Add to my webpage". I tried copying the generated code again (which looks the same as before) but even that did not work.
Even the new products I added are not reflected. Creating it afresh will probably work but I am experimenting with the style, and also intend to add/remove products on an ongoing basis, so every time I change something I don't want to recreate the widget. Any idea what I am doing wrong?
Have you republished your widget after the changes you have made as it is described in here?
UPDATE: (from OP's comment) I checked with their customer support and understand it is a known bug in their system. The workaround is to copy it to a new widget and delete the previous one. That works but is a tedious process if you have to make the changes frequently
I am developing the user interface for a embedded device. I have created about 30 ui forms. You have first the Welcome form which loads the database and connects automatically to the available known wifi and all those start up functions. Once everything is loaded the next form to be loaded is the user login
So this is how I go about it, if Login is my second ui
//Instantiating the Login class
Login *myLog = new Login();
//Close the welcome class
this->close();
//open the Login class
myLog->show();
Is this the right way to switch between multiple UI? The software can be imagined like any smart phone device with multiple Icon buttons to open different apps. And each app or folder has a functionality of its own. I have a home button to move back to main menu homepage and so on. I have used the above given code to switch between various ui forms and I am not sure if this is the way to go about it. I am very new to Qt and I was asked to do this task within 2 weeks and I created the easiest way I found. Is there a better way to go about it?
Any help or guidelines is appreciated. If you could give me links to understand better it would be great
Thank you
EDIT
Every ui form has a short cut panel for direct access to login, main menu, settings-power options, wifi options (within settings). The layout flow shown under 1 is similar to 2, 3 and settings. Sorry for the ugly image. The two way arrow indicates i can switch back and forth. The single arrow shows linear movement.
Is there a better way to go about it?
I think so.
As noted in the comment, I would use a QStackedWidget myself.
I think this blog post explains how to establish "Home", "First" and so forth widgets inside it. This should be useful for you:
How to use Qstackedwidget in Qt (Switching between multiple views in Qt)
I have made my own GUI API for games. One assumption that must be made is the user may want to use a derived version of a Widget I have made.
An example of how I dealt with this with ToolTips is, the user allocates a new ToolTip and sets a global one for the GUI. Ex: getGui().setToolTip(customToolTip);
The GUI then calls toolTip->show() when necessary. The problem with menus in general is that you can have many of them appearing at a given time.
I also would hate to have the user implement an interface:
PopUpFactory::createPopUp()
PopUpFactory::destroyPopup()
How is this usually dealt with? Who or how is the memory also managed for these?
There is always the option of limiting to something like 9 nested menus and have the user set an array of 9 PopUps but that seems messy.
Thanks
I've been wanting to program a simple game with a simple GUI using Qt (Its will be a VERY simple game, nothing fancy). What I've been wondering is, how can I create multiple windows and display them when needed? For an example, a battle screen and an inventory screen. The user should only see one of them, but should be able to access the other one when needed. I was using stacked widget but I'm not sure if that's the proper way. Also, is it better to design the windows in the designer or to code them?
A StackWidget certainly would accomplish what you want to do. The reason why it is not always used for this kind of thing, is that it all the screens are pre-created at the beginning and always exist. This means it takes a little longer to initialize, and you are using more resources than you need at any one time
But as you are saying, if this is a simple game, then I don't see a big problem with it. Just as easily, you could also, create an empty layout and swap the inventory and game panels as needed.
Add my vote to everyone else suggesting to use the designer. It is so much easier to manipulate layouts, actions, and such using the designer then through code.
You can see the Designer manual here
So this is what I would suggest:
Create your "battleScreen.ui" - which is the designer file for your battle screen and everything in it, and then create your "inventory.ui". Both of these could be QWidgets, or QFrames, or whatever makes sense.
Then create your "Game.ui" which will be your QMainWindow.
In your Game main window, you can then add your QStackWidget, and place your inventory, and battle screens in the stack widget.
If you don't know how to do that...
1) drag a QWidget into your form (into the stack widget)
2) select the new QWidget and right-click.
3) Select "Promote to..."
4) Fill out the information to promote the QWidget to your inventory class
Promoted Class Name: The name of your inventory class
Header File: The header file of your inventory class
5) Click add
6) Click Promote.
Hope that helps.
Since I'm not sure what your goals are I can't advise whether or not the stacked widget is appropriate but I think you can accomplish quite a lot using the designer and style sheets. If you need to code some parts of the GUI, you can always drop in a place holder widget and either replace it with coded items or make them children of the place holders.
A general answer for a general question:
Use the Designer to create your windows; hide and show the auxiliary windows as needed.
Use a flow manager class to manage the visibility of a related set of windows.
The stacked widget is useful for managing a button/icon whose appearance changes based on state; the different representations live in the stack.
I have been away from C++ for a couple of years now doing AS3/Flex work. I have gotten used to being able to create a component and place it in design mode with very little fuss and I am struggling to get my head around the C++ Builder way of doing the same thing.
I have written many components for C++ Builder in the past, but none of them have been visual. What I would like to do now is create a component for customer search and another for order processing because I want to be able to create a new instance of these on the fly. What I don't want to do is have to place each of the components like the dbgrid and search fields manually in code. I would like to do this (as well as set their properties) in design mode.
How do I go about this? I have browsed the source for other Delphi components and I notice they have dfm files which seems to be what I need. How do I do this in C++ Builder? The only option I see is to add a new form if I want a dfm, but this isn't what I want as my components will be based on TPanel.
Is there a way to do this or do I have to resort to doing it all in code with no visual reference?
Pursuing the DFM idea I did a test this morning where I created a component based on TPanel and added a new form to it which I create and parent in the constructor of the component. In design mode I set the form border to none and placed a grid on it. This all looks OK until I place the component in my application, at that point it looks like a panel with a standard looking form in it and the grid is missing. If I run the app the panel shows as expected, borderless and with a grid. The DFM appears to be ignored in design mode for some reason.
If you know a better way to do this than using components then please give me some pointers.
Any help and advice will be appreciated beyond words
You might want to have a look at frames (look for "Frame objects"). They are "subforms" you can design visually and then place on forms.
Just as an FYI item, you can also drop the panel on a form, put any other controls on it, position them, set captions, etc..
Now, click the panel to select it, and use Component->Create Component Template from the IDE's main menu. This creates a unit you can install as a component which will add the panel and it's sub-controls (as a single component) to the IDE's component palette.
Of course, you can then modify the source for that new component like any other component source.
