wxWidgets Discussion Forum

Dear all, With Mac OSX applications, it is common to be able to switch an application to a kind of full screen mode so that it uses another "desktop". Once applications are extended, it is possible to switch from one application to another by using three fingers on the touchpad and switchi...

Dear all, I would want to integrate a scanner interface to my MAC application, but as I am a noob with cocoa stuff, I looked on internet for an example. I found an application that nealy does what I want, but it's a xcode project implemented in objective-c and written as a standalone application (ht...

Thanks doublemax for your help. I tried to follow the tips in the link you provided to me, but it did not worked. But I am not really sure that the problem comes from there : I am not bothered by strings encoded in wxWidgets code. I am concerned about the dialog button ('yes', 'no', 'cancel', etc.)....

Dear all, I am porting my wxWidgets application to mac and I have a problem with the dialog buttons : they are in english whilst my Mac system is in french. On windows, not problem : the dialog buttons were always displayed in the language of the OS, but it seems to be frozen to english in the MAC v...

Thanks, it works like a charm

Dear all, I have a parent window containing several children (text entries, wxStaticBitmap, etc.). In some cases, all children are deactivated and I would want to intercept the mouse click events from the parent to perform some dedicated actions. I tried to bind a wxEVT_LEFT_DOWN to the main panel l...

Dear all, I have a problem when providing size constraints to some components. I want to compute the minimum size needed by an element for displaying it in a more complex viewer. I simplified my gui structure so that now, this element is only constituted of : - a wxPanel containing : - a wxBoxSizer ...

Dear all, I have an application that I use for several clients needs. Depending on the client, the configuration of the application is not the same and, for some of them, additional plugins are used to provide additional services. Currently, everything is statically compiled in a single program that...

The crash does not occur in the empty grid-bag: it occurs in the grid-bag that contains the empty one. And my old app had also empty grid-bags without any problem. It seems that the problem occurs when the grid-bag has only sizers that do not have any elements to display in them. Some parts of the c...

Probably, but I don't understand the assert... Here is the message: F:\AMS\wxWidgets3\include\wx/sizer.h(810): assert "m_cols" failed in wxGridSizer::CalcRows(): Can't calculate number of cols if number of rows is not specified (1a5c.4c28): Unknown exception - code 00001976 (first chance) ...

Dear all, I have a code that dynamically changes the structure of a window. When I add some elements, the application crashes and I cannot figure why. I wrote a simple code that simulates the behaviour of my main application and I am able to reproduce the problem. In this small test application, whe...

Hello DoubleMax, Yes, you are right : my problem comes from the fact that I post my custom events too quickly and wxWidgets does not have time to empty the other events (including gui ones). I digged into the code to understand why this did not work and, by doing so, I think I found a proper solutio...

I've never used it, but you could try wxApp::Pending/Dispatch I added this in my main thread job handler and it highly improves the situation. But I stil ldon't like this solution because I have the feeling that it just hides an underlying problem : for me, the way events are posted should prevent ...

Hello DoubleMax, Thanks for your help. My application performs database synchronisation. All operations that perform update of the database trigger a callback mechanism. The gui elements can register on those callbacks and perform operations on it (typically: refresh the gui if they display the elem...

Hello everyone, I am developping an application that uses 3 threads : The main gui thread One for sending data on a socket One for receiving data from the socket Some operations triggerred by the reception of data on the socket need to be performed in the main thread. In order to do so, I buffer tho...
