Hi Texus.

The center alignment when more than one lines exist, in my case in "buttons" but i can think that the same happening in "labels" also since "buttons" uses "labels", has not
correct align. All lines keep the first line start position. But each line has different count of chars.

It would be great if this would be implement at least in the new version of tgui. This, it would give me an extra motivation to start using 0.8 version sooner

cheers

Yes, it was my mistake, sorry again.

I should use "WS_EX_OVERLAPPEDWINDOW" style, since i was dealing with 'exstyles' and not "WS_OVERLAPPEDWINDOW".

This little silly mistake produce wrong mouse events.

Cheers

Sorry, texus it is not a tgui poblem. I am getting wrong mouse cordinates when changing the view. It is a sfml issue. Invastigating.

Sorry again.

I test the hitting by additing two breakpoint inside the "connect" signal functions of the two buttons. When i hit the 'back' button the program stops on the breakpoint into the
'ok' button and vice versa. Also, there are colors the down state in buttons .

Hi,
i found a strange bug. Really can not say if this is sfml or tgui problem but is is happening on button widjets when changing size and view on sfml form
along with changing the alpha color of form.

here is the repro project
http://www.mediafire.com/file/d2nadgdqb9wstw9/Tgui.rar

Code Select Expand


sf::Uint8 alpha = 80;
HWND hwnd = mWindow.getSystemHandle();
SetWindowLongPtr(hwnd, GWL_EXSTYLE, (GetWindowLongPtr(hwnd, GWL_EXSTYLE) | WS_OVERLAPPEDWINDOW) | WS_EX_LAYERED);
SetLayeredWindowAttributes(hwnd, 0, alpha, LWA_ALPHA);


if i use the above lines then when i hit the left button the signal goes to the right button and vice versa. Strange, isn't it?
Hope Texus u come with any idea.

thanks

Ok, thanks, i will try it.
Question: It does matter what tgui version i ll use? I am using the 0.7.5 one in my projects.

Come back to share a solution to my problem. Definately has to do with old drives of intel. But as long as i did not managed to find proper good drivers for this old "gigabyte"
motherboard, i was still looking and digging forums and source codes. The problem is the old opengl version and has to do with the context of rendertexture. The solution was to deactivate context of sfml's window and activate it just before displaying the context. Did some tests and now i do not have any issues.

here is the solution for tgui canvas

Code Select Expand


//-----------------------------------------------------------------------
sf::RectangleShape line(sf::Vector2f(1, 800));
line.setFillColor(sf::Color::Black);
line.setPosition(sf::Vector2f(0, 1));

pWindow->setActive(false); //pWindow is the main sf::RenderWindow

pCanvas = tgui::Canvas::create({ 5, 300 });
pCanvas->setPosition(200, 70);
pCanvas->clear(sf::Color(194, 206, 200));
pCanvas->draw(line);

pWindow->setActive(true);

pCanvas->display();


here is the solution of creating sf::RenderTexture without crashing

Code Select Expand


                pWindow->setActive(false);

sf::RenderTexture *pTex = new sf::RenderTexture();
pTex->create(128, 128);
        SAFE_DELETE(pTex);

pWindow->setActive(true);


hope it helps

Confirm that is the rendertexture. Can not be deleted once it created. Has nothing to do with tgui.

thank u Texus for your time. Cheers

Moving things to main function did not help. Also loading formmore in update function (create a boolean  to set it true in connect function and then create formmore in update function) did not work.

Well, debugging the test project, the problem is when the shared pointer is destroyed in memory file (_Decref() function). This happen only for canvas widgets and only in windows 7. Also the opegl version is 2.1. Well, i am not sure if it is tgui or sfml or vga drivers (opengl) problem.

Ok, made an simple app (find some time) that behaves just like my other app. This app crush only in windows 7. I will debug this code as soon as i find time.

http://www.mediafire.com/file/u6u5zo8njlrbmdg/Tgui.rar

http://www.mediafire.com/file/e7wxjzj5dildwzs/Test.rar

the same test app in the same windows 7 64 bit machine but with differrent vga drivers produce a message box about "createsurface : 3" just when i create second form (u have to have a look at the code)

The crash occurs when u exit from form 2 back to form 1. i am using visual studio 2015 for ide.

Tomorrow i will have some more news. If u want something just ask.

I do so texus and make a minimal project that reproduces the problem. As i said the problem occurs only on windows 7. Not in windows 10. GAME_MANAGER is a global static object. cForm is a private pointer in an onother class header (cForm* pForm;). So i create a new cform object.

pForm = new cForm();

and the problem occurs when SAFE_DELETE(pForm);

#ifndef SAFE_DELETE
#define SAFE_DELETE(p)         { if(p)      { delete (p);      (p)=NULL; }      }
#endif

Hi.

Well this time it is a crush. I installed my app to windows 7, 64 and after some tests i realized that canvas widget causing the problem. I removed it and the app stop crushing.
I am using a lot of different widgets but only this causing the problem. I have install a lot of versions of vga drivers and the problem remains. Maybe there is some version that stops the problem. Of cource, the crushing happening only on win 7 64 and not on windows 10, 64.
The code snippet shows when the crush occurs. (on destroy)

//cpp

pCanvas = tgui::Canvas::create({ 10, 800 });
pCanvas->setPosition(330, 70);
pCanvas->clear(sf::Color(194, 206, 200));
pCanvas->draw(line);
pCanvas->display();

GAME_MANAGER->getGui()->add(pCanvas);
}

cForm::~cForm()
{
GAME_MANAGER->getGui()->removeAllWidgets();

Any clue mates?

It is good enough for me Texus and i understand perfectly your worries and thoughts.
In first place i added my issue to "feature requests forum category", and i have no expectations to improve 0.7 as you been already to 0.8.

Certainly i start using 0.8 one day. That's for sure.
In attachment there are some photos from my latest project. Configuration forms has been made with TGUI.

Hi Texus, glad to hear that 'step' and 'floats' are implemented in 0.8. I ll stick to old cause i think is mature and stable. I 'll try it when it finished.
I do not know if you understand me. I can put negative values to slider but i can not make it, to have the positive value on upper side and the negative
value on the down side (i am using vertical align). In my case i set (min = -20) and (max = 20).

Hi Texus.

I am trying to make a sound equalizer with vertical sliders to adjust low, mid , high frequencies.
However there is no way to set positive number to up and negatives to down side of sliders.

pSliderEqMid->setMinimum(-20);
pSliderEqMid->setMaximum(20);

Photo shows better what i try to achive.

Also, it would be great, to have a step value for slider (i know is a mess).

Ok Texus. Now it is clear to me. Cheers

Yes the background color is working but not for the space between buttons. The background color should fill the space (SpaceBetweenArrows) with the defined color. In my case is grey.
If, still you can not replicate the problem, let me know. I'll make a test case and post.

In photo i am using
pButton->getRenderer()->setBackgroundColor(sf::Color(193, 204, 199));
without textures

Forget to mention that i 'm still using 0.7 version.
Tried your suggestion but still not working. Maybe is because i have long distance between arrow keys.
The image show my spin button (upper draw). The down spin button is the one setting null the textures.

Hello Texus

I tried "spinbutton" but setBackgroundColor,  setBackgroundColorNormal,  setBackgroundColorHover not working nor from txt file, neither from code.

Also, what is the difference between setBackgroundColor and setBackgroundColorNormal?

Suggestions: It would be great if a step value exist. Also, a text shown with the current value in between buttons as optional would be great!

thank you.

Hi.
When i add some buttons to my grid widget, i use the center align (default).
However if i use removeAllWidgets before i add my buttons to grid the alignment is getting top-left.

I use the 0.7.4

Code Select Expand

pGrid->removeAllWidgets();

int index = 0;
for (unsigned int row = 0; row < 2; ++row)
for (unsigned int col = 0; col < 2; ++col) {
pGrid->addWidget(pGridButtons[index++], row, col);

One solution is to use this code insted of "removeAllWidgets()"

Code Select Expand

auto& widgets = pGrid->getWidgets();
for (int i = 0; i < widgets.size(); i++)
{
pGrid->remove(widgets[i]);
}

Yeap, it is working..
Cheers

Use memcpy instead:
memcpy(pchData, LPCTSTR(m_contents.toAnsiString().c_str()), m_contents.getSize()); it works


Also a GlobalFree i beleive is missing from get(). Not sure...

it crashes here
-->strcpy_s(pchData, sizeof(pchData), m_contents.toAnsiString().c_str());

Yes, i can select the text in the text box.
How can i help u more?
